1/2" at 100 out of my Mini Mauser, doesn't seem "sub-par". No malfunctions out of a WASR or Maadi. Maybe it's the rifle you are using?
I never said I was using it in my rifles.
(I'm not)
I'd love to see some more information and evidence for TulAmmo legitimately shooting 1/2" at 100 yards.
The last time I heard something that amazing it turned out to be a single "3 round group with 1 flyer" (seriously)
