I switched from Norma with LRP pocket to Lapua SRP pocket. ES/SD did drop. The Lapua brass is very nice. Wish Lapua made 6GT brass too.

I shot a few over 42 grs of Rl16, Peterson SRP brass, and CCI450s out of a 28" Bartlein. Was getting 2845 fps. Trying to decide between them and the 140 ELDM for a NRL Hunter match. I would need 2715 fps for the 140, 2815 fps for the 135, and 2924 fps for the 130 Norma to make power factor.Anyone shooting 135 A-Tips over 4350 or similar? Looking for approx. velocity.
I get SDs under 9 with about any load of Rl16 and Peterson SRP brass with CCI450s. I also have a jug of 4451 if I run out of RL16. Had good luck with 4451 in my 260 when H4350 was unobtainable 4 or 5 years ago.I am about to invest in some quality brass. I would like some input on large vs. Small primers for 6.5
I have a keg of rl16 and 100v, also 1k each of 147eldm and 140match burners.
24" barrel
Ranges 600 to 1200
Suggestions welcomed
I have the Hornady and alpha 6gt brass. I have finally fire formed all of it so I can compare. I am leaning towards the alpha for the GT.I switched from Norma with LRP pocket to Lapua SRP pocket. ES/SD did drop. The Lapua brass is very nice. Wish Lapua made 6GT brass too.
The smaller case head is stronger. Less primer pocket stretch I believe. I have 200 cases on their 26th firing. Primers still snug.I've noticed many top shooters going with SRP but can anyone tell me why. I'm a math and physics guy. I like numbers.....
I just wanted to thank everyone for posting all of this data. It has really helped me a lot with developing a load of my own. I'll post results when I finish development.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.
Im new here so im still finding my way around. Ive seen it before then couldnt find it i just have to play around on here and figure out all the threads or forums i guess thats what their called. Im actually new to this whole kind of platform where everyone can chime in on all the different topics.You might want to check out the 6.5 Creedmoor load data for ARs only thread

nice. tried to go more with mine but started getting pressure so stopped at 41.6. tried 30thou off the lands and got nothing working so will be staying at 20thou nowI throated out a 26" Proof so it would jump 147 ELDMs 85 thou from a 2.900" COAL. I was getting 2830fps from 45 grs of RL26 out of Alpha SRP brass. Switched to Alpha LRP brass and the same load shot up to 2900fps! Just backed it down to 44grs and 2820fps.
Anybody ever tried once fired brass that was shot out of a different rifle that even after FL resizing with .002" shoulder bump would not chamber in your new barrel?
I have like 1000 pieces of once fired hornady brass that was shot out of two factory 6.5 creedmoors along with a couple 100 pieces of Prime. The prime I could not get to chamber in my new barrel at all with anything less than .004" bump. The hornady will chamber like 90% of the time but is snug and 10% wont chamber at all with .002" bump.
Factory ammo runs smooth. Once fired brass that was shot in the new chamber runs smooth. I have checked it with headspace gauges and it passes. When I sharpie the old brass that was shot out of the old rifles it is clearly sticking around the base of the case. Just wondering if there is possibly a problem with this barrel or if it is just a tighter chamber when compared to the ones in my old rifles and I will just have to use new brass that was fired in the new chamber? Any insight is greatly appreciated.
Thanks!
Yea so 1x fired in my gun is 1.532" I dont remember exactly what it was 1x fired out of the old rifles but I know it was longer. But bumping them back to 1.530" I am still running into issues. I am trimming them all to the recommended length 1.910" I think. I have tried bumping some significantly more even down to 1.526" which is about all my die will do and still run in to the same issues with some of the cases. Sounds like a small base die would be my next step.Yes I have...did you measure 1x brass that WAS fired in your rifle and compare measurements to brass in question to see where the problem lies? Might have to bump more...small base die....need trimmed....only you can answer those questions

Yep I sharpied a couple of them and am getting about an 1/8" ring around the base of the case so Small base should fix me up. Will give it a try. Thanks!Yep then that would leave larger base which you can just buy a small base die to fix...
Easy way is to sharpie the case and chamber...see where it's rubbing....you can wipe the case clean to remove sharpie with running alcohol
Hornady brass... Probably the problem. Voice of experience.Anybody ever tried once fired brass that was shot out of a different rifle that even after FL resizing with .002" shoulder bump would not chamber in your new barrel?

Yea was considering buying some Lapua but I have so much of this stuff I hate not to use it.Hornady brass... Probably the problem. Voice of experience.

Been there.... I had a 1000 new cases I finally sold.Funny I have a few thousand pieces of Hornady 6.5cm I bought when it was the only game in town for 6.5cm.. never had a single issue in shit 10-11 6.5cm barrels in both my custom gasser and bolt guns... still shooting it today...refuse to use any other 6.5cm brass till I shoot all this Hornady out..
Absolutely nothing wrong with it. The Indian or the chamber are the issue 99.999% of the time

In the situation of a stockpile of brass that didn't workYou been where?
In the situation of a stockpile of brass that didn't work
Yes sir!!You're still not answering the question... didn't work why? You said the OP problem was Hornady brass.. but have yet to say why. You fire brass in a looser chamber then try and use it in another chamber that has a match or tighter chamber of course its not going to fit. That's not the brass fault

I just recently picked up some small primer brass ive always used large pocket brass. Can i keep my loads the same to start off and just do a little load tweaking as i go or do i need to start all over with the small brass. Question#2 i see alot of people switching and using mad. Primers wether it be 450s or 215s. How much of a difference does the mag. Primers make and pressures do the produce. I would like to try them out being that i have tons of them. Do i need to start a complete load ladder from start to max. Or do they not make a huge difference. I know i will have to work my way thru some components to get the particular load my rifle likes but ive been using all 210ms and BR. Does someone have any insight they would like to help out with or some data using mag primers large and small. Thanks
Ok so i should just work up a completely new load with the small pocket brass and i figured if i switched to mag. Primers i would do the same i knew i couldn't or shouldn't start with my reg. Load i was thinking if i just went out of the hornady book and started in the middle of the feild and work my way up. I see so many people using the mag. Primers im guessing theres a good reason for it so wanted to give it a try.No. You should always drop down and work up changing any component. Small rifle primer brass is generally thicker, less case capacity so generally have to drop down your charge
Like with my blackout loads if i go out of the book it says SRP and a certain charge is max with reg. Primers then i look at hodgdons site and there charges are way up there and using mag. Primers on top of the heavy charges and my loads got so much better in every way possible so i was thinking this might be the same caseNo. You should always drop down and work up changing any component. Small rifle primer brass is generally thicker, less case capacity so generally have to drop down your charge
Anyone have some load data for 6.5CM, H4350, Berger 153.5gr?
This is what I got from Bob Blaine at Berger for the 153.5. Will try them out next week when I am home. I bought some loaded ones from Berger and they shoot very well at 100-200yds so far(new Sig Cross) so far. 2548fps. SD7
Anyone have a good 153.3 Berger Load with lapua brass and H4350? Thinking of running this for NRL hunter.
Haven't tried them with 4350 but I'm getting 2833 with 43.8 of rl16. 22 inch Columbia River arms barrel. Barrel has always been a little slow but it shoots awesomeAnyone shooting 135 A-Tips over 4350 or similar? Looking for approx. velocity.
Just before Christmas, I had 100rd loaded up and went to sight in my rifle after a hunt for the new ammo. I shot a couple rounds and then started checking the brass. And there the signs were. I started getting pressure signs and hard lifts. I stopped after 12 rounds. Looks like I have to go back to a lower node and everyone was correct. A node I found was at 2,544fps at 41.6-41.9gr of H4350. I saw it initially but it just seems so slow. I really want more speed. I am going to try this range again to see if the velocity is correct and if my barrel is speeding up. It only has about 120rds through it.Here’s an update.
I went to the range today to find a for sure upper limit. I found it and I saw ejector marks. I didn’t get to the speed I was looking. I saw them at 45gr and around 2,730fps. I stopped.
I did load some ammo and adjusted the seating depth based on previous ladder test. It looks like I am going to shoot 43.9gr.
My powder and primers are about 2yrs old. They have been stored in my safe and in my air condition house. I know that can make a difference but I’m hoping it isn’t this time. I have almost a whole 8lb jug and 2k primers.
My barrel is a Terminus profit cut by Straight Jacket Armory and it’s their SAAMI chamber.
I am going to load my rounds and hopefully next trip sight in my rifle. Happy shooting.
Loaded up 5 rounds to test after running through a small base die and everything ran perfect... Thanks!Yes I have...did you measure 1x brass that WAS fired in your rifle and compare measurements to brass in question to see where the problem lies? Might have to bump more...small base die....need trimmed....only you can answer those questions
Is there any reasoning why a slower burning power would get my speed out of a short barrel? It seems like a slower burning powder would need a longer barrel to generate the speed. You are shooting a 20in barrel, correct?@shax2lex - no to your last question, but here's some data I just finished yesterday using 140gr ELD-M's with H4350 and RL17. I've settled on loads at the lower nodes shown on the attached graph. The 2554 value on the H4350 was the first shot - cold powder, barrel, about 30* F.View attachment 7781980
It’s the Bergara BMP with a 24” barrel and a Hellfire on- if that matters. That (barrel length) is likely the difference.Is there any reasoning why a slower burning power would get my speed out of a short barrel?

Got 8 pounds of superformance local today. Have cci 200 primers and 142 smk anyone else running this combo??
