Did you clean the chamber/barrel before shooting your new gun? If not, clean it. Get rid of the stuff that was in their to prevent rusting before it got sold. You run the bolt dry with, at most, a drop of light oil on the bolt rails. 15-22s are not ammo fussy but are fussy about how the mags are loaded. The rds need to be staggered. You can't just hold the follower down and start dropping rds in like you can on single stack magazines.
