Small Ring On Base of .30-06 Brass
- Thread starter Shooter2675
- Start date
I saw a small ring around the where the primer would go, and it is no more than 2 mm thick, from the primer pocket outward. It is almost a slightly different color, and if I run my nail across it, I can feel a small lip. I am afraid I might have ruined the brass. Any help would be appreciated.
PPU, I do not have a PPU case, there is no shortage of 30/06 cases beyond that if they were USA made. I Have 30/06 cases that have rings around the primer pocket all Remington. Again, I know nothing about a PPU case, you could have an artifact that was there from the beginning, it is possible someone saw the ring on the Remington case and then decided to tighten the primer by smacking the case head with the letter 'O' letter stamp. Then like Little Jack walked off thinking they discovered a new method and or technique.

I'm trying to read your photo best I can.
IMO,it does not look like the rim pulled back,as has been suggested.
You can look at your shellholder.The shellholder will look flat,and correct,or it will look flawed,with a step in it to match the depression.If it looks right,it is right.
Same with your bolt face.
I doubt you have a problem with either.
I agree it does not look like any primer crimp I have seen.....But,PPU is made offshore,and no telling how they might do things.So I'll say "It could be a sort of primer crimp I have never seen"
I see a shiny ring at the very top of the primer pocket,and maybe some little curly chips in the pocket.
So,I ask,have you swaged or chamfered that primer pocket,or is it as decapped?
If so,you may use a mechanical pencil or a very sharp pencil as a probe.Place the tip down inside on the wall of the primer pocket,and draw the pencil up the wall,out of the pocket.Feel very carefully for any "catch" on the underside of that shiny ring.
If you feel anything,it is some funny foreign primer crimp.
That other pic of the .223 shows a PPU crimp,but on a .223 small rifle primer.
On your,what? 30-06,it may be a different appearing crimp.It is notable the .223 PPU is crimped.
Also,if you have any unfired ammo from the same source,examine it carefully.
It may be harder to see on virgin brass.Try a straightedge.
See where that takes you.Let us know.
Is it the one case,or all of them? If it is one,or a few,I'll agree it could be some flaw failing in the brass.
I hope you understand the brass is what keeps the over 50,000 psi hot gas from splintering your stock,shearing off your fingers,tearing chunks of flesh off your face and blinding your eyes.
Just something to think about.Brass is pretty important.
If you do have one or a few show this as a flaw,I'd scrap them all.
Its kind of like that potato salad you forgot to put in the fridge.Dang.Good potato salad.Only been 7 or 8 hours.Hate to waste it.Sure do like potato salad.
Might be near a whole dollar worth.
You ever had food poisoning?

Correction, I have a few Frankford Arsenal cases with the ring around the primer. The Remington cases were loaded in Connecticut.
