This is a discussion on Crimped .308 Primers within the Reloading forums, part of the Defensive Ammunition & Ballistics category; Which company's sell loaded ammunition with crimped primer pockets? I know of Lake City. What about others like CBC, American eagle, Winchester, pmc, etc... Jabraun...
Which company's sell loaded ammunition with crimped primer pockets? I know of Lake City. What about others like CBC, American eagle, Winchester, pmc, etc...
Typically, only military ammo has crimped primer pockets. Obviously contract over-runs and "seconds" reach the civilian market, but I am not aware of any commercial ammo from the majors (Federal, Winchester, etc.) made for the civilian market that has crimped primer pockets. It's an additional manufacturing step that's of little or no value to the civilian shooter.

Crimped primers are military contract. Lot of surplus ammo from other countries have crimped primers. I've got some Greek and Egyptian that is crimped.

You will need to remove the crimp before reloading the brass; I have used the RCBS primer pocket swagger for many years with good results. It is an extra step that only needs to be done once.

I've got a box of CBC and was wondering if it was crimped... And I've got some of the other brands listed in my first post and I try to avoid crimping when I use that brass to reload.
Crimped primer pockets are done that way for military ammo for use in fully automatic weapons to insure function. No use for us mere civilians.
All the brands you mention have, from time to time, over runs from military contracts and these are usually crimped and often sealed. I have never "personally" seen LC or TW that was not crimped. As to American Eagle, WW White box, PMC and Federal White Box, some is some isn't. I am not familiar with CBC.
You can swage the crimp out or ream it out. After thousands of rounds each tried each way "I" prefer reaming.
It's pretty easy to tell if the round is crimped, just look for an offset circular indentation around the primer.
