I shoot a Winchester 9422 in .22 Mag. Had some problems with one of the Winchester specialty loads a few years ago (wouldn't eject an unfired round (head space problem?)) anyway, use the CCI Maxi Mag solids for everything now with good success. Took a young coyote this fall at about 80 yds. with good results. They are great on squirells too even if I miss the head shot, they come down quick.
