Overruns from federals LC production and or didn't meet LC govt spec and was simply loaded withotu the crimp for sale to the public instead of military.

Only other LC brass that I"m aware of that doesn't have crimp is military LC match ammo and though I'm not sure but suspect now that match ammo is allowed in combat, I suspect even the LR stuff has crimps.

We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
