Start of case separation??????

[Chesterrose79]

So I have a 6.5 creemoor and I've been reloading with lapua brass. So far with this brass I've done load development and have had some pressure signs. I'm on my third firing with these. Last firing I seen these rings and shot them anyway. Nothing happened and I am happy with the results. My question is. Am I sitting on a ticking time bomb? Should I scrap these? I checked the inside with a paper lip and felt nothing.

That brass isnt far from separating

It looks like it, but most separations I've seen have been closer to case head.
You might be able to see it with a small flashlight, although the .264 hole might make it a bit hard. I wonder if your brass is finally expanded to tightly fit your chamber and you've got a small "scratch" that's leaving the mark on the brass?


What is your sizing procedure??

I'd bet that ring is from the loaded rounds sitting in your ammo box. How do you store your ammo?

Looks like a crack on the left side below the shoulder. Lol I bet it's from being in your Ammo box like ^^^ said.

Normally, an incipient head separation shows as a wide yellow looking ring about a 1/4 or more up the case.
That shiny ring is from an ammo box where during transport the case rotated as it rattles around. I bet if you check it will be adjacent to the top of the tray.

Hope this eases your mind.

Cheers.

Did you notice it prior to or subsequently after firing? Likely from ammo box if you see others that have the same ring and not been fired. You should have noticed it prior to loading if it had been there. If it really bothers you, sacrifice a piece of brass and cut it in half. That should settle it once and for all.

The ring is too low for that. The bullet sits in a 100 rnd case and they sit deep in it

Looks like another use for a bore scope.

Not sure about the ring, but frankly, I would be more worried about the crack as noted above.

It's been there for a couple firings. Didn't think much of it till I seen a thread on here about a gentleman having a case separated

Well that does look like a crack! I'll have to inspect them and make sure. Thanks

Looks like a crack to me?

I honestly think they're scratched from my sizing die. Every one has the same marks and it doesn't extend onto the shoulder towards the neck. They're all same length and pattern.
