Borrowed some of my buddy’s 140gr ELDM’s, loaded up my standard load and boom, .8” group. I’ve burned about 80 of these Bergers and feel like I’m chasing a load that isn’t there. Just frustrating. Think I’ll just stick with what works.

Anyone have any data for a 17" barreled creed? Not looking for blistering speed just accuracy and consistency. Finally able to start shooting again and need to get out and get started.
Planning on using h4350 for power and starline SRP brass
Every day is a decent day, IMO to go shoot. I always realize my limitations when the wind is howling. One of these days my skills will improve, I’ll just keep trying.I loaded up some 143 hornady eldx and some 130 hornady eldm rounds. Charges were 41.0, 41.5, 42.0, 42.5 . Will see what happens.
Have to say that using a chargemaster lite makes loading rounds so much quicker and easier!
Now to wait for a decent day to go shoot. Sitting today at a lovely 65° but over 20 mph winds with gusts of over 35.
I shot some of my 47.8gr rl26 with the hornady 147 ELDm yesterday. This is all show from a PVA built ARC nucleus with a 26" barrel, with a griffin paladin 30 cal can. Average over 25 shots was 2985 with an ES of 22 and an SD of 7.6. Would obviously like to get those lower but it shoots as good or better than I'm capable of. .5" all day long at 100yds. I have yet to go to distance with it, but that velocity seems ridiculous, measured with a LabRadar so should be accurate.
6.5 CreemoorJust to confirm: What caliber/chambering, and how long is the barrel?
BTW: I maxed out on the 153 Atip at about 2700 fps in a Savage 6.5 Creedmoor. Heavy bolt lift and flat primers at 2730 fps, at 88 degF. Lapua bras, CCI 450 primers. Used RL-17, because i have a lot of it sitting around. It usually gives me 150 fps more than H4350, but VERY temp sensitive, so a winter and summer load has to be developed, which wastes time components and barrel life. [Not recommending RL-17 as there are better options, like RL26.]
Plan to try RL26 soon.

Hi all anyone trying Winchester stable 6.5 with nosler 140 rdf
Lancaster ca I go there a few times a yearYes. And are you from Lompoc?
Lancaster ca I go there a few times a year
Ya I searched it found one on here I loaded some starting at 42.5 thru thru 44.4 haven't been able to get out to dang.hot tyI grew up there is why I ask.
There was a whole running thread on 6.5 staball. I'll have to look but I'm pretty sure thats what I used for testing.
How long of a barrel are you running to get 2825 out of 41.1 grains H4350. My experience with Hornady 6.5 brass is it runs a slower with an equal charge. My Hornady averages 53.5 gr H20. My Lapua averages 52.3 gr H20.Finilized a load for my MPA BA 65CM finally. I abandoned SW Precision (Varget) due to pressure issues with garbage FPS
140 ELDM BTO 2.165 (.030 jump)
41.1 H4350
F210M
1x Hornady
3 shots around .2
AVG 2825 FPS
SD 4.7
ES 9
I dint have a great node to play with but right at 41.1 the groups tighten up real nice and the numbers were fast enough with really low SD/ES so Im running it until my annealer and mandrel come in

Between that length and that temp I can see that kind of speed. I too find the Magnetospeed to be accurate just wish it wasn't a tuning device. I'm running 41.8 gr H4350 140 ELDm 205m @2778 80* 1300 elevation. There was another node at 42.5 but it wasn't as accurate. This is a 24" barrel.26" MPA (xcaliber) with "match chamber"
those numbers got me thinking too now that you mention it. the day I shot that string was 96* out. I shot a match over the weekend with that same load and the morning zero range sesh on a buddies lab radar showed 2808 so I ran that speed for the morning split....it was a balmy 45* that morning. I started to miss more during the day so I upped my speed a touch in my kestrel and it didnt help much.
I just loaded another batch with that same recipe and going to launch them Thursday. we will see. My magneto speed has been checked twice against a lab radar and they are always been within 4 to 8 FPS from one another.

I'm in the process of building my 6.5 Creedmoor and I have a few boxes of their 120gr AMAX factory loads, but once those are gone it to the table. I've seen a few loads on here, but they are spread out all over the place. Figured we need a spot for all of them to go. Bullets I'm interested in using are: 130/140 Berger VLD, 120/140 AMAX, 123/139 Scenars, 142 SMK, and 142 Matrix. Haven't decided powder yet, but mostly will go wth H4831sc or H4350.
Oh nice I haven't pulled the trigger on the stand off. Thinking about just going Labradar. H4350 is supposed to be temp stable and from what I've seen it is within reason. I know for sure that elevation and atmospherics play a big role in your dope. My zero shift between a density altitude of 1800 and 2600 is 1 MOA and from my notes it's about a 20 fps change. My velocity I stated earlier was not correct. Now that I'm looking in my notebook my velocity at DA 1800' was 2762 my velocity at DA 2600' (home) is 2746.may magspeed is mounted off the barrel so I have that going for me for impact results. I was assumed H4350 was temp stable but a 50* swing with an elevation shift I suppose that sort of change can be expected... ?????

2 inches should give somewhere around 60 fps change flat out. Other factors would be internal ballistics ( case capacity from different brass, case capacity differences from sizing operation, my lot of H4350 could be moderately slower than your lot, primer lots, etc.) Atmospheric difference, DA difference, elevation, this could go on forever. I'm not too sure what change elevation gives. I would imagine it's significant but density altitude is significant. The elevation difference between the two DA locations I listed is around 300' but where I live has a significantly higher average humidity so my DA goes up alot. I did a small batch ( 5 shots each) test with 210m primers and CCI 250 primers and my average velocity was 16 fps difference, my extreme high was 24 fps. Same lot brass ( unsorted Hornady). So one could argue if I had sorted the brass and took the high case weight ( smaller case volume ) cases for both my average could have been 24 fps. Say I went opposites, my average change could have been ~50 fps. Granted I wasn't really loading this test for precision, just slapped it together.interesting. I havnt really paid much attention to the DA .. I will start recording that for when I travel for matches...
so your mid 2700 with more h4350 than me and your barrel is only 2 inches shorter. 2 inches isn't giving me close to 100fps gain. wonder what gives
Lapua is nice brass. I would not interchange your Hornady load to Lapua. It most likely won't blow up in your face but my Hornady Brass held and average of 53.5 grains H20 internal case volume and my Lapua holds and average 52.3 grains H20. Also you are dealing with different primers. I'd drop back a couple grains and work it up. I don't know of any instance you would want to just swap 1-1 on a load for any component change whether it be cartridge components or interfacing gun components.First time Lapua brass user.
Small primers and flashhole:
Is there anything I should consider about this?
Have only loaded Hornady brass in the 6.5 Creed so far, large primers and flashhole.
Can I just overtake those loads?
(As a side note: Man, is that Lapua sweet-looking or not?)
I would not interchange your Hornady load to Lapua.

Thanks for sharing your experience and thoughts.
MPA has a min spec chamber, so less “chamber volume”. I get the same speed (2750 fps) in my MPA 6.5 BA with 1.3 grains less powder (H4350) compared to my Savage 12. Pressure signs show up about 1.5 grains earlier.
The extra 2” adds about 40-60 fps over a standard 24” barrel, depending on what powder you use.
The min spec chamber reamer was apparently chosen to ensure Hornady 140 ELDM match ammo shoots really well in this gun. And it does that. Meant for folks who want to compete in PRS or NRL with an off the rack rifle with factory ammo. In my case, factory Hornady ammo shoots really well, around 0.4” five shot groups or a little less at times.
Accurate rifle and fun to shoot. One side effect to take note of is that thicker brass like Alpha and Lapua does not always provide sufficient neck clearance. Pretty tight neck. I ended up neck turning my premium brass down to 12.1 thou (was at 14-15 thou before), to ensure a bullet will freely drop into EVERY case post firing.
Free bore is also short to ensure the 140 ELDM is seated at a small jump, so loading anything heavier than a 140/144 gn causes the bullet to intrude way too deep into the case, eating up case capacity and pushing pressures up. The manual also says not to shoot the 147 ELDM factory ammo. It will likely cause high pressures, and i have no intention of trying that.
Good rifle, very good ergonomic chassis, but really meant for one weight class of bullets only. With proper hand loading, you could of course develop a safe load for the very heavy 153/156 bullets, but the bullet will be seated past the donut area at the case/shoulder junction, so important to ensure the cases are donut free and loaded rounds have good concentricity.
Effect of case volume on 6.5 Creedmoor velocity - some experimental data
OK, have been wanting to run this experiment for a while, and finally found the time 2 weeks ago. Have been collecting range brass over the past 4 years and just kept it in a plastic bucket, never shot it since it is unsorted, different manufacturer, different batch and different weight.

Inspired by your writeup in the other thread, I just measured weight and length of my Hornady, Norma and Lapua brass.
WTH!!!

I guess I got lucky with my 200 pieces of Lapua. The whole lot only had 1.1 grain spread. Very consistent H20 volume too. Didn't bother with any of it on my Hornady because of past experience in a different caliber. Have 200 pieces of Alpha waiting on a barrel to show up so I'll have to see how those are.I did trim them to the same length (where again Lapua was there right out of the box), chamfer them with a mandrel inside, turned the necks on the outside slightly (just to remove the burs at the mouth) before I weighted them.
Norma was actually very close to Lapua, being about 30% cheaper as Lapua I´m curious how they will perform.
Hornady was all over the place, unbelievebale.
I measured the weight of 20 of each brand.
Lapua´s biggest difference was 1,1gr., Norma was 2,1gr. and Hornady was 9,4gr., I was shocked.
