Love the 22 mag, my favorite was a 512 that I really regret letting go. I bought mine primarily for skunks and coon. It was great out 150 or better on prairie dogs, a lot of helicopters but not much better than 40gr LR. On large animals. Most if not all manufacturers use the same bullet in the mag as in the LR and I believe it is just too soft for the extra velocity, expands or comes apart before decent penetration. Federal 50gr with the slower velocity may do the trick, don’t know as I no longer have a 22 mag, but a body shot on the larger animals with the 40 gr soft lead pushing two grand leaves something to be desired
