Was just out at the range with my sks and my handload was not functioning in the rifle, but it would fire it would not push back the gas piston to eject the round. I had some factory ammo that functioned fine so it must be my load. I am using 123 grain soft point .310 bullets and 23 grains of IMR 4198. Does any reload 7.62x39mm with 4198 if so i would appreciate some guidence. Thanks!
