Not one started so figured I would.

Berger 140g Hybrids
51.2g H4831SC
26" 8.5tw Bartlein M24/40
COAL 3.218"
2990fps +/- depending on lot of powder.


Caution, this will not fit a standard 6.5x55 chamber. COAL is too long. You'll need a lot of throat. Barrel started to go after 2400 rounds. Ending COAL after chasing the lands before the barrel burned out was 3.232.

Just out of curiosity, how many firings were you getting on your cases before they wore out??

Glad you made it over from the old site. Not sure most of the other 6.5x55 fans did

I got 6 firings before the brass started dropping primers. It's a hot load for sure. I also anneal every other firing.

I'm running 50.6 gr of H4831 sc under 140 hybrids at 2860fps out of a 24"bartlein.



Im on my 7th firing of the brass with no issues yet. Hoping to get one or two more before the brass goes and ~3000 out of the barrel.



Layton, I'm jealous of 2990!! You must be adding some secret sauce.

How is your muzzle flash? That's a lot of slower burning powder for a short barrel.



I have a 22" Bartlein that will shot both 123 and 140 AMAX's with 48.1 gr of 4831SC. The barrel harmonics are just right with that amount of powder.

I had a good 123 Amax load with a former 6.5x55 I had. It was a CZ 550 Full Stock.



Keep in mind, the barrel was 20.5", which certainly hurt the velocity and the "throat" wasn't too long.



My load was:

Lapua Brass

CCI 200

123 Amax

COAL in my rifle was 2.530" to ogive - measured with Hornady L-N-L (.010" jump)

46.5 grains H4350

Avg MV = 2768 fps



I worked up to 48.0 grains averaging 2850 fps, but the accuracy node was lower and it was showing some slight pressure signs that high. You ought to be able to go way faster than that with a custom tube and a properly set up throat/chamber.

Thanks for the info. I am trying to come up with a load for a factory Win 70 featherweight in 6.5x55 so I am dealing with only a 22" tube. I tried H4350 to start with and didn't have much luck but that was with some different bullets. I will give this a try and see how it goes. Thanks for the info!

KElblys - 6.5x55 GWI

just now fire forming so that load is essentially a std 6.5x55

24" Brux Barrel

46.5 IMR 4350

Wolf Mag Primers

COL 2.92

130 Berger Hybrid

2810 fps

Mild flattening of primer



Honestly a little surprised at the slow speed. I think I will try 2.94 OAL and bump up to 47 gr see what happens.

Was hoping for 3k but barrel could be a little slow. Will be happy with 2900. Not sure half grain can get me 100 fps tho. Maybe 50.

DT

Just shot the Vegas Precision Rifle Challenge while fire-forming brass. Rifle shot amazing almost pulled out a top 10.

Velocity sped up to 2925 once barrel was broke in, more where I expected it to be.

Cant wait to work up a load for the GW Improved. Will keep updated. Hoping for 3100fps

ETA:

Forgot to mention that when I chrono first time it was -10 at a match in the mtns so that might have skewed data some

yes it sucks working up a load in the winter but you do what you have to lol.

I'm putting together a 6.5X55 improved throated for 140 Berger hybrids. Wondering what loads to start with, and where you are seeing pressures? What powders are working?

Great thread , I'm just starting to reload for my Sako Bavarian Carbine. I'll be watching here for some ideas



What powder would be best for the 20" barrel. I pretty much have all powders for this caliber. Kinda saving my H4350 for my Creedmoor though...

This isn't really the spot for it, but I figured someone who has posted here might have a pair of go/no go gauges for 6.5 x 55 I could borrow. Have a savage action build with a Shilen barrel that's completed and shoots well for the most part, but gets pressure signs earlier and with less powder than anticipated.

It was built and head spaced with a more knowledgeable friend and we used a factory Lapua round for the go and added a piece of electric tape for no go. I would like to borrow a set of gauges if available and check out spacing to see if that's possibly the issue.

I will gladly pay shipping for anyone that can help me out.

Thanks

Hello everyone,
Krieger HVT 28"
minimum spec. chamber, classic throat
Tried the new 147gr ELD M bullets.
Lapua brass, 6X loaded
CCI BR primers
45.6 gr. IMR 4831
3.160" OAL
Average velocity 2860 fps
LabRadar chronograph
Max load

 

[Ritterbruder]

I just completed some load development for the Swedish Mauser and thought I'd share my results.

This load shot well in a '43 Husqvarna M96 long rifle (29' barrel) and in a '41 Husqvarna M38 short rifle (24' barrel).

Lapua Brass
CCI #200 Primer
Alliant RL-17, 42.1gr (warm load)
Hornady 140gr ELD
Seat to 2.600" base-to-datum with Hornady comparator (~10-15 thousandths off the lands in both rifles)

These rounds will fit in the magazine but you cannot load with stripper clips.

Chronograph results with a Magnetospeed V3:
M96 long rifle: Average 2660 fps, S.D. 8.1 fps
M38 short rifle: Average 2610 fps, S.D. 7.5 fps

RL-17 seems to burn a bit fast for the 6.5x55. I think a slightly slower powder would yield better results. Will update post.

Hey all,
I just picked up a TikkaT3X Hunter stainless fluted in 6.5x55 with their 22.4” barrel. It seems that H4831 or 4831SC might be the best powder. I don’t have any of that but do have Reloder 26. Anyone using RL26?

I may have some data for you... It has been a while since I did much shooting with my 6.5x55 but it seems like I did a little testing with this powder. I will have to check my notes when I get home tonight.

Virgin Lapua Brass
Federal 210 GM primer
51.5gr H4831SC

I am in process of gathering 6.5x55 components to load. Will be loading for Ruger no. 1 in 6.5x55 with 28” Douglas light Palma barrel.

Came across this today. Best price I have seen in a while. 6.5x55 Lapua brass .73 per piece!! Thought I would pass along.

Another military load in case someone is interested. This one was capable of MOA accuracy with iron sights in two Swedish Mausers (M96 and M38).

Lapua Brass
CCI #200 Primer
Alliant RL-23, 46.2 gr
Hornady 140gr BTHP
Seat to 2.600" base-to-datum with Hornady comparator (~10-15 thousandths off the lands in both rifles)

Rifles tested:

Swedish Mauser M96 long rifle (28.5" barrel)

RL-26 is probably too slow, especially for your barrel length. RL-23 or H4831(sc) are still the best choices. You can also use RL-16 or H4350 and get great velocities, but your load density would be low.

[blisters]

Does someone have a receipt for the Berger 140gr with N165?

I haven't loaded that particular bullet, but in a modern action 45 to 47 grains of N165 should work. It has for me in both T3 and Blaser with 76 mm (2.99") COL (Nosler BST and Accubonds).

Take it easy and work up your load properly and pay attention to pressure signs of course. N165 is a tad slow for 140 grains bullets, you would probably be better off with N160, but N165 does work. You may see some soot on the case necks. For speed, go with Norma MRP (substitute with RL-22 if MRP is unavailable).

 

[Hetzer]

This thread needs a jump start.

RE22 @ 46.3 gr @ 3.150 COAL
Federal GM210 primer
Norma case
Lapua 139

Avg's 2752 fps with a 10 SD.
Pics are five round groups at 100 yds. Did some scope zeroing and testing for velocity.
Next is probably 20-30 rounds at 300yds through the ShotMarker to see if it holds up.
This was through a Tikka Sporter- 23.5 inch factory barrel

 

[Modoc]

Reading and following this thread. I was just gifted a late war Husquavarna that has been part sporterized and needs completion. Then off to load development!

 

[Megastink]

I’m also following this thread. I have a ‘37 Mauser 98 that I had rebarrelled with a 1:9” Brownells barrel in 6.5 Swede. I have a stockpile of 120gr Hornady GMX’s, and a mild recoiling deer killer sounds fun! The only powder I have that’s listed in Hornady’s manual is H4350, but I have a good bit of 4831SC as well, so I snooping those recipes.

Just started load development for a short barrel military build:

Gunsmithing - Peruvian Mauser 1932 bolt shroud question

I was looking for a small ring mauser action for a 6.5x55 swede build and fucked up and bought this weird small ring k98 action. Its a rare action per my research. Only 5K rifles made for Peru. Chech Bruno Modelo 1932 carbine in 7.65mm. Can anyone tell why this bolt shroud does not have a...

www.snipershide.com

My focus is on lighter bullets, specifically 100 and 107/108 grains. I have an older Lyman reloading manual with loads developed using a 18" Swedish carbine as a point of reference. They call out IMR 3031 and IMR 4895 for their 100 grain loads. I've elected to use H335 since its burn rate is very close and I have it on hand.

Pretty impressive results. I've got to be on the high end of the pressure scale but cant be sure without using something like Quickload which I don't have. Don't see a need to go any higher with these results:

100gr Amax 5-shot average @43.0 gr of H335 is 2958 fps with a SD of 10.
107gr SMK 5-shot average @42.0 gr of H335 is 2877 fps with a SD of 31.
108gr Scenar 5-shot average @42.0 gr of H335 is 2904 fps with a SD of 13.

Point and shoot out to say 250-300 yards is my goal for this hunting/truck gun.

 

[GIXXER2000]

I have a Steyr SSG-04 that needs a new barrel so I am thinking of going 6.5X55 with a 28 inch 1-7.5 twist barrel and throat to shoot Berger 144's .147 ELD-M ,150 SMK or even the 153.'s. I currently have a Merkel Helix in 6.5X55 that shoot great but it has a 22 in barrel with 1-8 twist. It a hunting rifle but I really like the cartridge and see a lot of potential for a heavy barrel precision rifle.

 

[nrspence]

Anyone know of a good 6.5x55 AI reamer that will work with the Redding 6.5x55 AI full length sizing die? In my searches I’ve found a lot of different swede ackley improved variants.

 

[tho98027]

I'm currently shooting a 6.5x55 Improved 35 degree shoulder. Has a 70 thousand freebore. I'm shooting berger 130 hybrids 3050 fps with 52 gn of H4831SC in a short action, 23" hawkhill barrel braked. Coal is 2.96" and bullet jump is a couple thousands from the lands with that coal. Bearing surface of a 130 hybrid is above the neck/shoulder junction. Using an accurate mag without the blinder plate. Will only hold 4 rounds in a 5 round mag. Using a surgeon 591r action that has had the bolt face opened up about 10 thousands. I've been impressed with the accuracy of both the fireforming loads, 140 berger vld jammed 7-10 thousands w/44 gn of h4350 and my current load with the 130 hybrids. Virgin lapua brass holds 57gn of H20. Fireformed brass that has been resized holds over 62 grains of H20. Respectable improvement in case capacity. Would like to eventually build another in a long action and have it throated long to seat 140s-150 class bullets to 3.150-3.200" and see what this case can really do. In a short action I'm already impressed with the velocity and accuracy. In a long action, I'm sure it would rip, especially with a longer barrel. I'm curious to see what my barrel life will be. Reading a lot of the forums, it seams the swede improved has twice the barrel life of a 6.5x284. Go figure. We'll find out.

Good info, thanks for sharing. I’m waiting on a reamer to be made from manson in 6.5x55 imp 40 degree should. I went with a .170 freebore since I’m using a Tikka long action. If I can push 140 weight bullets at 3000 I’ll be very happy.

 

[tho98027]

You’ll hit 3000 easy. The 6.5 addiction which is a 37 degree improved Swede with a 10 thousand freebore shoots Berger 140s 3000 fps in a short action.

My reamer print.

 

[tho98027]

I've looked at a lot of reamer prints for the swede AI and Improved versions. Everything on yours looks good. Might see if its possible to change the base/P1 from .479 to .4794 , I know that is not much but I had a 6.5 gwi that was giving me clickers and the base was too tight in the web at .478. Sammi is 4794. So I came up with my own reamer design with some changes over the gwi print. .479 will probably be fine, but if Manson hasn't machined the reamer yet, might pass it by them to make the change on the print. Sometimes all it takes is 1/2 thousands for clickers to go away. Just my .02.

Might see if its possible to change the base/P1 from .479 to .4794 , I know that is not much but I had a 6.5 gwi that was giving me clickers and the base was too tight at .478. Sammi is 4794. So I came up with my own reamer design with some changes over the gwi print. .479 will probably be fine, but if Manson hasn't machined the reamer yet, might pass it by them to make the change on the print. Sometimes all it takes is 1/2 thousands for clickers to go away. Just my .02.

The diameter at the bolt face is .4808 the .479 is .200 forward of the bolt face.

 

[tho98027]

Correct.

 

[tho98027]

Just sharing my .02, take it with a grain of salt.

 

[Hetzer]

I went with the GWI in the "Long" variation. Converted a T3 .30-06 to it with a Brux barrel. Still in some fire forming stages but I'm happy with it thus far.

Good to see some others working this cartridge.

 

[tho98027]

Did Kelbly build it for you?

Let me know if you need some dies.

 

[Hetzer]

I had JGS make me the reamer from the Kelbly prints. And custom dies from Whidden.
The rifle chambering was done by Moon at Crescent Customs.

Appreciate the offer though.

 

[XLR308]

Glad to see this thread active again as I have been very interested in converting my Tikka T3 in 270win to a 6.5x55 or one of the improved versions.
I measured my bolt face and it has more than enough clearance, no surprise there and my Kelbly actions are close but still have .002 of clearance on a once fired Norma case.
Not really wanting to do the short version though it is doable on the Kelbly actions and using the Alpha mags i have with plenty of clearance.
Most interested in the long action with the Tikka, i have checked overall length with 140 Hybrid and 150smk with the full diameter just above the boat tail at the neck shoulder junction in the Tikka mag and there is still a very generous amount room in the mag.
I just need to decide which of the variants i would choose going forward.

 

[nrspence]

It sure is tough deciding what variant to go with. My gun smith Jeremy Smith up in Oregon should be getting my reamer here soon to spin up my barrel.

 

[XLR308]

It sure is tough deciding what variant to go with. My gun smith Jeremy Smith up in Oregon should be getting my reamer here soon to spin up my barrel.

I reached out to Redding about if there is any particular reamer or print they would recommend over another that would best complement thier custom 6.5x55AI die set that would work the brass the least.
Since they offer that variant that is the way i am going.
Im still a ways out but will source components, dies, reamer and decide on a barrel most likely a K&P and still not sure what stock yet.

I asked Redding the same thing, and the reason why I went 6.5x55AI.

Just out of curiosity did they just recommend the standard reamer or any other suggestions on slight changes to dimensions ?

 

[nrspence]

Take this for what it’s worth, but I sent them my reamer print and they said it should work fine.

 

[Modoc]

Well, the project rifle is on the back burner for now. Need a new stock, bottom metal and? I did get my hands on a Swede in a full Manlicher style stock that I am going to be working with. Has anyone tried Staball 6.5 yet? Looking at the 140g Amax and 99g Hammer Hunter. May also go for the 123g offering from Hornady since it seems to have similar dimensions as the HH.

I'm also looking at replacing the Weaver K-4 that is on it with something else, but this is a hunting rifle.

Caution, this will not fit a standard 6.5x55 chamber. COAL is too long. You'll need a lot of throat. Barrel started to go after 2400 rounds. Ending COAL after chasing the lands before the barrel burned out was 3.232.

I'm running 50.6 gr of H4831 sc under 140 hybrids at 2860fps out of a 24"bartlein.



Im on my 7th firing of the brass with no issues yet. Hoping to get one or two more before the brass goes and ~3000 out of the barrel.



Layton, I'm jealous of 2990!! You must be adding some secret sauce.

How is your muzzle flash? That's a lot of slower burning powder for a short barrel.



I have a 22" Bartlein that will shot both 123 and 140 AMAX's with 48.1 gr of 4831SC. The barrel harmonics are just right with that amount of powder.

I had a good 123 Amax load with a former 6.5x55 I had. It was a CZ 550 Full Stock.



Keep in mind, the barrel was 20.5", which certainly hurt the velocity and the "throat" wasn't too long.



My load was:

Lapua Brass

CCI 200

123 Amax

COAL in my rifle was 2.530" to ogive - measured with Hornady L-N-L (.010" jump)

46.5 grains H4350

Avg MV = 2768 fps



I worked up to 48.0 grains averaging 2850 fps, but the accuracy node was lower and it was showing some slight pressure signs that high. You ought to be able to go way faster than that with a custom tube and a properly set up throat/chamber.

I tried H4350 to start with and didn't have much luck but that was with some different bullets. I will give this a try and see how it goes. Thanks for the info!

KElblys - 6.5x55 GWI

just now fire forming so that load is essentially a std 6.5x55

24" Brux Barrel

46.5 IMR 4350

Wolf Mag Primers

COL 2.92

130 Berger Hybrid

2810 fps

Mild flattening of primer



Honestly a little surprised at the slow speed. I think I will try 2.94 OAL and bump up to 47 gr see what happens.

Was hoping for 3k but barrel could be a little slow. Will be happy with 2900. Not sure half grain can get me 100 fps tho. Maybe 50.

Just shot the Vegas Precision Rifle Challenge while fire-forming brass. Rifle shot amazing almost pulled out a top 10.

Velocity sped up to 2925 once barrel was broke in, more where I expected it to be.

Cant wait to work up a load for the GW Improved. Will keep updated. Hoping for 3100fps

ETA:

Forgot to mention that when I chrono first time it was -10 at a match in the mtns so that might have skewed data some

yes it sucks working up a load in the winter but you do what you have to lol.

What powder would be best for the 20" barrel. I pretty much have all powders for this caliber. Kinda saving my H4350 for my Creedmoor though...

This isn't really the spot for it, but I figured someone who has posted here might have a pair of go/no go gauges for 6.5 x 55 I could borrow. Have a savage action build with a Shilen barrel that's completed and shoots well for the most part, but gets pressure signs earlier and with less powder than anticipated.

It was built and head spaced with a more knowledgeable friend and we used a factory Lapua round for the go and added a piece of electric tape for no go. I would like to borrow a set of gauges if available and check out spacing to see if that's possibly the issue.

I will gladly pay shipping for anyone that can help me out.

Thanks

JTG

Sorry if this comes up in the wrong place, just new to this site and my first post. Maybe I have read the conversation wrong about 6.5x55 barrel not really up to the job, showing signs of burn out. I'm I right is saying you are discussing the 6.5x55 Swedish?? I shoot a Steyr Pro-hunter 6.5x55 Swed. I have been shooting it for years hunting and targets. What I have found is with my rifle, it hates hot loads. H4831 -46g with Hornada SSTs 123g. However, VihtaVuori N-160 is the best. Very accurate in most loads. E.g. Lapua HP 139g with 42g - 44.5g N-160 powder. H-SST 123g, 42g N-160 best. Also I have been reloading the same Federal brass for ever. Sorry I don't know how many times I reloaded it, I just never though it would last this long. My last day at the range I did have to bin about 3 or 4 used shell, the first ever. Anyway, thanks for reading, let me down easy if I did the wrong thing posting.

 

[penguinofsleep]

Wasn't sure if I should revive this thread of create a new one -

From looking around online, it seems like Reloder 22, R23, H4831(sc), and N160 were amongst the more popular powders for a modern 6.5x55, non-AI or wildcat variant, with 140-150gr projectiles. Seems like Reloder won't be available in the US for a while longer, H4831(sc) is still relatively hard to come by, and N160 gives good results but slightly lower velocities.

Any other powders that someone should look at? Haven't seen other powders with a similar burn rate to the above pop up much when 6.5x55 is discussed for modern loads with the above projectile weights.

 

[Rider47]

I haven't read the other 39 posts in this thread, but while H4831SC was good in my Kostyshyn barreled 6.5x55 BR rifle, H4350 was significantly better. Also Berger 140 Hybrids tended to shoot better than SMK's. Not surprisingly, H4350 is the go-to powder for the 6.5CM.

 

[tho98027]

4831sc has been my first choice. h4350 is my second pic. re23 was so so. I've heard good things about re16 in the swede.

 

[Bergara HMR]

Just adding my experience with the 6.5x55 Swedish Mauser. I have been hunting and using this rifle at the range for about 20yrs. There's a very good reason I am still shooting and hunting with the same rifle all these years.
The rifle:
* Steyr Pro-hunter 6.5x55mm SM
* Barel 590mm (sub 23.5") Stainless Steel
* Twist 1:8

Load data:
I have use different powders, some Hodgdon powders are now band in the Uk and Europe due to risks of carcinogens.
I have used:
* H4831 Performance not near as good as N-160
* Vihtavuori N-160 By far the powder that performs best in my 6.5x55, using 120-140g bullets.
* Vihtavuori N-165 A slower burning powder than N-160 so not good with lighter bullets. Starts grouping bullets from 139g.

Listed below is some chronograph load data for the 2 Vihtavuori Powders.
* N-160 This by far is the best preforming powder in my rifle. Consistently shooting sub moa. On a good day 13mm (1/2") group at 100mtrs, just over 25mm (1") at 200 mtrs and 32 to 37 mm (1 1/4" to 1 1/2") at 300 mtrs, using a 120g Nosler BTBT bullet driven by 45.5 of N-160.
Chronograph showed:
120g Nosler BTBT bullet driven by 45.5 of N-160:
Difference in FPS 61
Average Velocity FPS 2831
Average Velocity M/s 863
Muzzle Energy ft.lbs 2135
Muzzle Energy ft.lbs 2895

123g Hornady SST BTBT bullet driven by 42g of N-160: (groups very slightly wider)
Difference in FPS 97
Average Velocity fps 2662.5
Average Velocity m/s 812
Muzzle Energy ft.lbs 1936
Muzzle Energy Joules 2,624

143g Hornady ELD-X BTBT bullet driven by 42g N-165: <<<<note different powder
Difference in FPS 146
Average Velocity FPS 2652.25
Average Velocity M/s 808
Muzzle Energy ft.lbs 2233
Muzzle Energy ft.lbs 3028
I found some inconsistencies in the N-165 test so want to test these again.
All the above test were done with:
* Federal brass
* Federal primers
I am still using the same brass from the 100 factory rounds I bought with my rifle when new. Only 3 have shown cracks on the neck so far.

I am currently testing Berger 140g Elite Hunter Bullets with both Viht powders.

While I do shoot targets with this rifle it is mainly my deer stalking rifle. It is a great calibre for hunting and I will always have a 6.5x55 SM as my main stalking rifle. I have shots many deer over the past 16-20 yrs. I shoot Sika and Red deer. Hinds and followers (calves) I shoot with 120g series bullets. While I have culled out a 12 pointer (called a Royal) Red Stag at 200mtrs with the 120g Nosler bullet, I would never do it again. The stag dropped where he stood but was not dead. Field dressing and butchering the animal showed the bullet fragmented. My assessment was part of the bullet went up and hit the Stag's spine, paralyzing him. While those with me, thought it was a great shot, honestly, I was lucky. However, the 140g bullets will bring down a Stag without issues. That said I now use a .308 for larger animals at distance.

One final point. up until 2 weeks ago I was having problems getting N-160. So was testing other powders to decide which one would by the replacement. However, my groups have not been as tight as I want. Now I will re-test with my new purchase of N-160. I note this because there may be 2 other variables at play here.
1. My barrel may have shot it best days.
2. Due to my age, I may have shot my best days too.

If you have read this far, thanks for reading and hopefully my input may add something positive to the debate.

Thank you for such a detailed reply.

Sounds ladder testing with N160 and IMR4350 (even though H4350 seems to be more popular for 6.5x55) for 139 and 147gr projectiles will be a good place to start. May try 123gr Scenars and finding some H4831sc if the above don't work but would prefer the above weight range + not having to look for powder.

[Hetzer]

I've been using RE22 but now have some N160 and 139g Scenars to try out.

 

[nrspence]

N555 is money in my 6.5x55 AI.

 

[penguinofsleep]

Brief update:

H4350 pressured out at minimum load with 139gr Scenar but worked very well (for me at least) with 123gr Scenar. ~0.3-0.4" at 100yd, slightly above 2800 fps.
N160 for 139gr/140gr and 147gr. Same group size at 100, but only got about 2450 fps with a 22" barrel.

Based on the above, is there any way to tell if N165 or H4831 would give the same groups with better velocities for the ~140gr projectiles or am I just going to have to try them both (given that reloder 23 is still not available)?

I'm sitting reloading at the minute, looking up old data:

H4831 LOAD 42.5g, bullet Lapua 139g Mz fps: 2382 - personally I never liked H4831. Groups ok but never close to N160.
H4831 Load 45.5g, bullet Lapua 120g Mz fps don't have it. My notes seem to show it grouped ok (all my H4831 data is old)
N160 Load 46.5g, bullet 120g Nosler Mz fps 2925 This was my happy load/group. I use a smiley face on my data when I'm happy. This load was shot 5 rounds at 200 mtrs. Overall group size 7/8", 4 rounds inside 1/2". Now you know why it's my happy load.
N160 Load 42g, bullet SST 123g Mz fps 2662 - Happy load
N165 Load 42.2g bullet ELD-X 143g Mz fps 2609 - tested twice Aug & Nov. group 1/2 MOA 200 mtrs.
N165 Load 42.5g bullet Berger EH 140g Mz fps 2514 - Current test, group inside MOA @ 100mtrs (currently can't get anymore of these)

Basically N160 has always performed best in my 6.5x55 (Pro Hunter barrel 590mm &1:8 twist). The only reason I used other powders is when I can get N160. The N165 does seem to work ok in the heavier bullets 140g+.

Not sure if that is helpful of not. Just my findings. One thing, all on my H4831 chronography test was the average of 4 rounds. I now do either 8 or 12 round to find the average.

The 120 gr otm Lapua ammo shoots great out of my 6.5x55 AI chamber. First five shots through the barrel.
