"Pinned" Lake City Primers?
3/27/2012 1:39:20 AM
Recently I've purchased two lots of Federal XM193 (lot# 170 and 212; both headstamped LC11). The 212 lot has four strike marks around the primer and the 170 lot does not. The only other difference (which I'm told does not mean anymore than packaging difference) is that lot 212 came in a box dated 2011 and labeled XM193F while the 170 came in a box dated 2005 labeled XM193. Not a problem, just wondering about the differences. I could not find anything in the ammo faq's for the headstamp primer pinning.

No worries, just a more "rugged" way of crimping that can withstand higher pressures.
The other lot is still crimped, its a wring around the primer pocket that is lower then the rest of the headstamp because it has been pushed down to crimp the primer.

I'm guessing federal did this in response to primers blowing out.

Possibly I am being confused by the photos but the two shells without the crimp look like some heavy hand reamed out a crimp. Any possibility that somebody is loading up some old boxes with reloads and passing them off as factory ammo? Do you remember where you got this ammo and if the box seemed like it was sealed up normally?
Sorry to stir the pot
Never mind, I now see the photo is in a reply,not part of the OPs question.

I think they made that crimp for M855A1.

I got them from Palmetto State Armory.

Thanks for the response. That's what I figured after reading old posts of primers blowing out.... I can see a recessed ring around the other rounds, but it does not look as solid as the other method. Thank you for posting the pic; that gives a perfect visual of what I was talking about.

I did that to show they can be removed just like the old crimp. The ones on the right are actually older brass that had the crimp removed. You can compare and see that if you remove the crimp like people have been for years it wont take any extra material away.
I'm 99% sure this new crimp is to deal with the much higher pressures of M855A1
