Like howl said, with a steady rest you should be able to keep it under half a Moa at 50 with decent ammo, wolf mt or me sk standard plus(same as mt) if you want to get a little pricey, my alltime favorite is r-50 from rws out of my 40x. Howl I dont mean to start things but mini mags are high vel not hyper. general rule for a more accurate 22 round is shoot a bunch of different types. My mini palma rifle hates wax lube rounds from eley and shoots great with grease type lubes found on lapua (sk and wolf). The tbolts are great rifles good luck with it.
