300RUM Primer Ring on Bolt

I have some 215's and can try them, thanks. It's certainly far from a severe crater but I was taught the same as you... craters are a sign of pressure. I just never thought theses were severe enough to be concerned with them.
I put a new barrel on it. Same reamer was used to cut the chamber. But it did it with the last barrel too.
That what I want to do! I just want to make sure I don't hurt her or risk any shooter safety.
I am setting up a Lee Loadmaster progressive for pistol and they have a warning - only use Remington or CCI primers in the primer. If you don't, you need the optional blast shield to protect from exploding primers. Seems only Rem and CCI design can withstand the pressure of being seated by the ram.
i am almost 80 and I learn something every day. Jim
Your good to go
I always load about 10% below max. I find that they are the most accurate - if I think I need more power I get a bigger gun.
Example, my Weatherby Mk V .300 can load to a max of about 3250 or a little more. I load to 3050. Know what? Everything I ever shot never moved after I shot it. Jim

I would suggest backing off to 86.0 grns and shoot three rounds each with three different primers I would try three rounds using 86.0 Grns with Fed215; Win LR magnum, and perhaps Rem LR Magnum . Three Shots each Primer. Total 9 rounds. Then clean the bolt at the bench then try 86.3 and again fire three rounds with each primer. Again 9 rounds and clean the bolt at the bench between each primer test. I would proceed until the ring in the bolt face re appears as you approach or hit the 87.5 load. If Only ONE Primer causes the ring issue, and you really need the 87.5 of H1000 grn load, then you now know that particular primer is not useful with that much powder, using that particular Bullet . I'd hate to see a damaged rifle for the sake of something like one extra grain of powder. Good Luck Buddy !!!

FYI, a cratered primer is NOT always a sign of excessive pressure…
If you have a firing pin hole that is beveled, you WILL see cratering at even the lightest of loads. Nearly every Rem 700 of recent manufacture have beveled firing pin holes. Look again at the firing pin hole.
Cheers.

That hole is not beveled. Zoom in on the photo for a better look.

Pressure in my book. Also a flat primer.

Good point
Thanks. I'm going to first load a couple light loads to even see if it's there with them and go from there.
Agreed. I don't think the hole is beveled at all but I will watch for this on other rifles. Thanks!
