i just got a ruger 10-22 last weekend from bimart (brand new obviously) when i took it out after i got it i noticed about 1/10th of the rounds fired would not go off, i went through about 200 rounds. after inspection of the rounds i noticed that sometimes the firing pin just wasnt hitting them hard enough and would barely put a mark in them. other then that it was feeding fine and everything else seemed great. i was using ccm mini mags through it. i got the all weather ss anyone else have this problem, or know of any fixes for this?
