I have shot a couple thousand rounds of mini mags from my 10/22.. i could probably count on 1 finger how many issues i've had with it. As a matter of fact, I can probably count on one HAND how many issues i have had with my 10/22 with all ammo that I have tried (and I have used at least 6 or 7 different kinds in it). Mini mags (RN and HP), Winchester M22, Remington GB, Federal HP bulk, Winchester SuperX, Winchester bulk (which, coincidentally is the kind i had the most trouble with, and by that i mean about 3 FTF's out of approx. 150 rds)..
Take your 10/22, shoot all sorts of different brands.. Chances are, you will have very few issues. Its a great plinking gun.
