help in reading pressure sign

[harry_x1]

Hi all - seekjing help from experienced shooters in help me reading the pressure signs on the primer. Attached pic are for 338 lapua manum - H1000 91.5 grain - 300 grain berger elite hunter bullet - shot from 26 inch barrell in an AI AXMC.

Bolt opens flaslessly, however I do see some cratering on the primer. Can some experienced folks tell me, if the amount of catering and primer condition, looks too dangerous and should I back down? thanks for your attention and time.

Which primer's are you using?

Don't see any ejector swipe and you say bolt lift is ok, so it could be an issue other than pressure. . . ???

Do you have any cratering at a lessor charge?

 

[harry_x1]

In lesser charge the catering reduces and around 87 grain it is goes missing

Primer is federal gold medal match..

Just like their brass, Federal's primers tend to be a little soft. So, you might try CCI BR-2's or just the CCI 200's. Or, you might even give Federal's 215M's a try.

If any of those give you the same results, then you might about bushing your bolt's firing pin hole???

And primer cup still rounded too. I don’t see any pressure signs.

(I’m not telling you to throw more powder)

You in a node you’re happy with?

Kind of .. thing is I want to shoot one mile targets and some articles on inrernet say, that for one mile you need to be minimum 2800 fps... hence trying hot loads, and seeking advice from more experienced loaders

Your primer and case head look ok to me except for the crater. That may be from a sloppy firing pin fit. I would be more concerned if the primer was flat or if I saw brass flow back into the ejector or extractor.
