Each .22 mag rifle, in my experience, is a law unto itself as far as ammo prference goes. Each one, even within the same brand and model, likes a certain type of ammo and I have never been able to predict which. My Marlin 882 likes Win 40 gr HPs as well as the Win Supreme HPs. It does not seem to like any of the other, higher-priced ammo with the various premium bullets. My Win 9422 likes the CCI "green" ammo and just about anything loaded with V-Max type bullets in the 30-35 gr weight. My buddy's Savage with a heavy barrel seems to like the 50 gr Federal ammo. My brother's old Mossberg Chuckster likes CCI 40 gr HPs.
Buy a box of each, as you can afford to, and try them out.
