I'll be the first to admit, I used to be firmly against running steel case ammo in ARs. I've had problems in the past, primarily running Wolf through a Bushy I had some time ago.
Never ran worth a damn. Once warmed up, it'd jam at least once per mag.
But recently I've started playing with it again. Found the cheapest of the cheap! "Herter's" made by Tula for Cabela's. About $130 for 500rds in a dry-store box.
I've run this stuff through BCM & RRA midlengths, and two PSA carbines. They all run just fine, and the "beater" PSA with a standard carbine buffer?
So... I was wrong. Lol, it happens.
