Have not shot herters, had a bad go with hangfires with some of their other ammo. But, from the Tula I've shot, and honestly might break some down to see if i get bored, I'd shoot and I could 2-5 rounds a bix that lacked enough ass to cycle either of my BCMs or even my Bushy. The rest would cycle, but damn even Wolf I have less issue with than the Tula I've shot. The only Tula I've managed to run multiple boxes without a fail to feed or in sone cases fail to eject with a spent casing in my chamber was the 75gr stuff. I will caveat that the last Tula 55gr FMJ I shot was 3 years old as far as when I got it. Newer might be more consistent. But the issues I've had I still consider it junk.
