I was the lucky bidder to win a 500 round lot of .223 PCA ammo which I was the only bidder to boot (I wonder why)!! It is head stamped with 04 which I know is the year & I did not research it too well. Lucky freakin me... eh I just shot some of it at the range with the new Bushmaster with a piston kit. What I found was that 2 out of 7 rounds fired I had 2 seperations (see pics). Personally I think they are crap & I will not shoot any more of this ammo & would like some options of what I can do to salvage this deal since I have 493 rounds left. Should I pull the bullets, save the powder & start over with new brass & primers? Any assistance from seasoned reloaders appreciated. Jim Sr.
