RE: WOLF ammunition
I shoot a lot of Wolf ammo the primers are harder than most brands , so if you have light primer hits you will have rounds not going off once in a while. So no light hamer springs!
Most people that have problems with it have light primer hits.
I have shot several thousand rnds each of 762 X 39 , 223 and 9mm. I will not call it match grade but it's not junk. Great plinking ammo.
Just so you know they use steel cases
