You busted me bacardi.. i'm actually an importer that deals exclusively with federal ammo.. i'm bad mouthing the norc stuff, so nobody buys it and i get rich..
but seriously folks, the stuff i have problems with comes in 40 round packs wrapped in paper.. there's no lot number on it, and nothing written on the wrapper.. i usually use the federal black box ammo (which i have a nice stockpile of) with no problems..
like i said before, i had shot at least a couple of hundred rounds of the norc stuff without problems previously, and just started having problems with the last batch of 200 rounds or so that i bought..
i used some yesterday in a 14.5 inch AR and lots of misfires (no hits on the firing pin).. i didnt get a chance to try it in my 20 inch AR.. maybe if i get out today, ill give it a shot.
there's no conspiracy here..
cr5: you are correct about the cleaning part.. i dont have any problems at all with the good ammo , after the bits of crap are cleaned out of the bolt..
