i'm sure anything you cycle after every round manually would be more reliable than a semi. my grandpa has a pretty reliable old pump 22 that's fun, although we pretty much just run cci minimags through it, although i think that's about all they have where he got ammo, up until he had to move to an assisted living. don't know where that gun is. If it's still at his farm, i'll snatch it, but i think my cousin may have it
