Home Forums Hunting & Shooting Deer Hunting 350 Legend upper

I have the same upper as you. The jury's still out on mine. The first time I shot it the cheap 155 gr WW FMJ ammo functioned fine but Hornady 170 gr Whitetail ammo wouldn't feed well and pierced the primers. Also the rims of all the fired cases had a burr around them caused IMO by a step on the bolt face. To BCAs credit, when I contacted them about it they had me send it back and it was returned to me within a week, all at their expense. The explanation was a defective barrel nut misaligning the barrel. I looked at the bolt and it's the same one with a step. I remounted the Burris AR536 and fired two Hornady rounds (which hit dead center) and the cases are burred and both primer indents are black. Not sure whether to pitch a bitch or try different ammo first. Might be it doesn't like Hornady? My other 2 AR bolts (.223 & .450 BM) don't have this step on the face so maybe I'll swap the bolt from my .223 upper and see if the problem goes away.
