My CZ shoots a 3/4" group of 10 at 50 yards with them, prone, no bipod. They aren't hollow point, but they do seem to kill gophers... I have had 0 misfires with them. I had quite a few misfires with remington, federal, winchester... The normal plinking and hunting rounds that aren't $12/50. I"d rotate those bullets 180 degrees, and try again, and they'd fire, leading me to believe it was the ammo, not the gun. The dimple from the firing pin strike was normal, so, I"m sure the gun wasn't at fault...
