just wondering if anyone has tried to run these yet...
COLT .223 62gr FMJ 500RD Case (RUSSIAN MFG)
62 Grain lead core full bi-metal jacketed bullet
Zinc plated steel case
Non-corrosive berdan primer
my LGS has a hell of a deal on them right now, 500 round case for $149...thought if M&Ps eat it OK I might get some for an upcoming weekend in the hills of Kentucky, hunting mostly squash and pumpkins...
