I have a question regarding ammo. I own a SVT 40 from 1941 and it almost refuses to run with surplus (but seems to like modern manufactured boxer primed ammo). I have tried cleaning out the inside of the bolt, different surplus ammo (Czech and Chinese) which has failures to fire where if you give the bolt a half #### and fire the same round again it sometimes fires and other times you have this heavily struck primer which won't fire. The half cocking the gun to try to fire the round again takes most of the fun out of the rifle when you don't even know if it will shoot. If someone has a trick to make it work with surplus ammo, I'm all ears.
Thanks
