This. My .22lr of coice is CCI mini mags. I have quite a bit of the M22 and introduced it to RennFab. I also use this federal target stuff thats pretty good too.This. I've been using that coper plated moly coated M22 ammo and it's damn good stuff, but if it came down to reliability, the Mini mags are the way to go. Stuff just shoot for 22lr, plain and simple.
