I saw a guy at Myrtle Grove have some real problems with Herter's. FTE, FTF. Ended up having a bullet stuck in the barrel. He was shooting a SIG FYI.
I put 100 rds of it through my M&P 15 on Sunday, and another 60 through my buddy's Bushmaster with zero issues. Someone (I think it was Clandestine) said if your gun wont run steel cased ammo, it's your gun, not the ammo
