6.5 Creedmoor

Has anyone tried the Berger 156 and RL26? I’ve got some that I want to load and need some charge weights. I’ve also got H4350 and 4831sc and several other powders but want to try the 26.
Im playing with the rl16 instead of rl26, the bigger bulelts seem to like it more and im getting the same speed. 42.8 gr is giving me 2752 with .010 off the lands
 
42.8 of RL16 was my load with 135 A-Tips but I could only get 2820 out of it with my 26" Bartlein. It was very accurate with low SD/ES. I moved up to 43.5 with 450 primers to get 2850+. Still getting 6 or less SD. Stupid accurate to 1400 yards so far.
 
41.3 H4350 in Lapua brass and cci 450's propelling a 140 ELD seated .035" off the lands of my JP Enterprise barreled mega maten build... 5 @ 100, best group yet for this rifle.

Started development with RL26 since I managed to score 2lbs from brunos. Shot with a 26" PVA built ARC nucleus BA, with a griffin 30 cal paladin can.

Virgin Lapua SRP
CCI#450
Hornady 147gr ELDM
Reloder 26
2.80" roughly .150 jump

46.5gr
AVG 2796
ES 23.73
SD 9.41
~.66"

46.8gr
AVG 2823
ES 24.23
SD 8.88
~.84"

47.1gr
AVG 2846
ES 20.1
SD 8.62
~.89"

47.4gr
AVG 2873
ES 16.5
SD 7.37
~.60 (4 shots, had one fail to go off)

47.7gr
AVG 2895
ES 32.12
SD 12.5
~.48"

48.0gr
AVG 2916
ES 30.87
SD 11.97
~.61"

48.3gr
AVG 2945
ES 29.9
SD 14.38
~.48"

Brass still looks excellent. No sticky bolt, and primers are still rounded. Bullets were deformed pretty good to get 2.80 even at 46.5gr. I'm thinking working in the 47.7-48.3 range. ES/SD weren't the best but had very similar POI.

Brass goes 46.5 on left to 48.3 on right.

Are these velocities correct? All with 147ELD?
 
Thanks.

I loaded up a few of the new Berger 144 Hybrids this past weekend using the same load for my 140 Berger Hybrids which are @2884 FPS. I am seeing some slight cratering on the primers and had a couple sticky bolts. It surprised me at the jump in velocity (expected it to go down). Seems really hot to me.

I plan on starting low again (40.5) and working up.

Lapua Brass
CCI 450
42.0 gr. H4350
Velocity 2916 FPS
.020 off lands (29" Shilen Match Select)
SD = 0 for my first 3 shots
SD over next 3 shots was 2.4 - I stopped there due to a couple of sticky bolts.

First 3 shot group was .361", second group was .496".

Is anyone else seeing a jump in velocity going from 140 to 144 Hybrids?

Thanks for the info man. I have lent heard much about the 150+ GN bullets out of a Creedmoor. I’d be curious to see if a 1:8 in a 16.5” short barrel would be fast enough to stabilize it. I would think a 1:7 or 1:7.5 would be ideal.

I may just run up some Barnes 127gn LRX for her rifle for hunting. My experience with the Barnes Coppers are pretty damn good when it comes to Terminal performance. They hit above their weight class.

I’m thinking some 4350 and 127gn LRX’s are gonna be the ticket for her hunting round.
42-43gr with .050" jump should get you close to ideal with the Barnes 127 LRX
 
Anyone have any load data using berger 140 elite hunters and imr4350 powder? It may be in here somewhere but damn my eyes are hurting from looking. Looking for some real world numbers if possible. Rifle is a bergara hmr pro. Just starting load development and h4350 is a unicorn locally. I plan on working up a hunting load and a match load and picked up what was available locally for now
Any help is appreciated.

This should help you get started.

 
Have been waiting on some R26 to get here. Of course, it is backordered. I do have a ton of R25. Is the burn rate of R25 pretty similar to R26 but more temp sensitive? Does anyone have starting loads for R25 and 130gr eld's. Just wanting to be able to load up a few rounds and hit the range with the 6.5
 
I'm on the verge of getting dies for my 6.5 Creedmoor. Simplex, a local Australian company, has very nice match grade dies but for some reason they only have neck sizing and seating dies for the 6.5CM.

I don't really want to neck size, so I wanted to ask what dies you guys are running. I do have my eye on a couple of full length options, but wanted to hear the consensus.

I may be the odd one outta the bunch here, but I run Hornady match dies ( bushing ) with my 6 and 6.5CM’s.

I use Redding bushings that are 4 thousands under where I want my neck tension to be, then use an expander mandrel with a 21st Century Neck turning arbor to bring it back up another 2 thousands.

This gives me 2 thousands concentric neck tension.

The entire setup cost me around $175. You can spend $250-300+ on dies if you want. I have Redding comp dies for other calibers and I cannot tell the difference in this process.

Are you getting that short of concentricity on the seated bullet or just the brass. My hornady resizing does give me great results but I get up to .0035 runout after seated
 
Rifle: Tikka T3x Tac A1, stock configuration

Load:

Prime Brass
FED 210M primer
Sierra 142 Matchking 1.37 length, G7 .303
RELODER 26 @ 46.95-47 grains.

JUMP: 0.100.... yes 100 thousandths, 1 tenth of an inch. OAL is 2.815 or SAAMI length.


2830 FPS, SD 5, ES 20. Rounds touching during zero and velocity trued out during a match LOL.

Tried 47.2 before the match: accuracy and SD'S went to shit.
 
42-43gr with .050" jump should get you close to ideal with the Barnes 127 LRX

I loaded up a ladder test with Barnes 127 LRX's last weekend from 42.4-44.0 grains with RE 16. 43.8 and 44.0 were within 4 fps and clocking in at 2905-2909 in a TC Compass (21.6" barrel). I've got brass drying now from cleaning those cases. There wasn't any pressure signs at 44, so I'll start at 44 and work up this weekend. I'm using Hornady brass, Redding Type s Match bushing dies, CCI 200's. Seating the bullets 0.050" off the lands.

Have any of you guys ran imr 4451 under a 140gr Berger vld target bullet? Had a great node at 42.3gr 4451 with a 140gr eldm. So I’m hoping for similar results but figured I’d ask.

@Steel head might be using 4451
I burned about 12 pounds of it in my previous 260 barrel.
I actually liked it more than H4350.
You have to burn about a half grain more than H4350 to get the same speed but it has a bit more head room and good case fill.

Best groups I ever got were with 4451 and 140eldm’s

Considering the case volume difference your at about the same place I was.

Just scored another 8lbs of reloder 26 from a local shop for 159.99. Was the last one they had. 1 lb were 23.49 had 2 left of those. 16lbs should be plenty for me for a LONG time, should last the rest of my barrel life, roughly 500 on it currently.
I wish I could get the 8lbers for $159.99. I would definitely buy them out.
 
What is a reliable load for 6.5CM using R16 and 140gr ELDMs?

I switched powders from 4350 and need a decent load to break a new rifle in. Just want something that will do ok like the tried and true 42.5gr H4350 loads are.

I’m using Lapua brass.

In my 260 I use the almost the exact same charge of H4350 as I do R16 but the R16 will be faster.
If you have a mild load worked out for your brass and H4350 I’d just swap in R16.

Getting ready to start some loads again after swapping to a 17" barrel. I have bought some starline brass and have seen some reports that it produces higher velocities than standard hornady brass.

Was curious if anyone was using this brass and if you had any suggestions on powder size. Have a bunch of h4350 so planning on using that.

I'd be interested in seeing what velocities you are able to get from the 17" barrel.
 
I shot an 18" for PRS last season. I got a bit over 2900 with the 123s (SMK/ELD), and 2600-2650 with the 140ELD/142SMK/143ELD. All using a comfortable load in Peterson brass. I don't remember what the 123 load was, but the 140 class was 41.4g of H4350. Not exactly a smoking load. I could have pushed harder but my groups were always between .25-.5 MOA.
