I was set on Magtech steel-cased ammo, but the Fusion Firearms 2011s do not like it. I know it’s the ammo and not the guns because they’ll eat any other brand of ammo.
I bought 1000 rounds of Remington 124-gr FMJ (green/white box) to address the FF issues of failing to return to battery.
I tested the Remingon by shooting 200 rounds of it through the XP Comp. The XP Comp ate it all without issue.
I shot the rest of the 1000-round batch of Magtech through the AF Attila.
I don’t believe in every gun having to accept all types of ammo, especially if some ammo brands are out-of-spec.
