Aloha All
Just wanted to post this here to see if anyone has anything similar happen to them. With this powder/bullet combo. Thanks in advance!
Have a buddy who hads a 6.5 PRC giving him issues on a hunt right now.
Here's his load specs:
New adg brass,
F215M
60gn h1000,
Berger 156 eol,
coal 3.0735,
cbto 2.360 = 15 thou off the lands
He told me he spoke to berger to get chg weights for H1000 & this cartridge/bullet combo. He was given 54.5 start 60.4 Max. He did note that they wouldn't give him brass brand they were using.
He did load work up from 56-60.5, 60.5 had very slight bolt lift resistance, Not heavy etc! Settled on 60 gr load less than .5 groups.
Below is what he had from LR for velocity. Until yesterday he had shot roughly 30 rounds with no pressure signs etc. Temps here are mid to high 80's
So he checks zero yesterday before today's hunt and first 3 shots all blown primers heavy bolt lift. He's scratching his head and bummed because he only took 20 rounds of 143's with him which he's already shot 10 lol.
Only thing that comes to mind is if the ADG Brass has a different volume than what berger was using (I'm thinking hornady?) Therefore the ADG Max is less than what berger is using. BUT...he worked up loads and none showed high pressure signs.
Idk what ppl seeing for velocity with this bullet but I told him that what he's getting is up there. But idk much about the PRC. I have a 6.5x284 n only doing 2950 with 130's.
He's got meat in the cooler so I told him I'd try and ask if anyone has ideas on the forums.
Sorry, his rifle is built on a tikka action. Started out as 300 Win mag. Had gunsmith rebarrel it with a proof sendero 7.5 twist 26" Put it in a woox exacts stock l believe.
