As others have said, it's just another .22 LR and will fire in anything rated for that caliber.
Since I've started tracking all of my ammunition usage, I will say that Mini-Mags are problem free and one of the few .22's that has been. They're really best in semi-auto pistols since they tend to have the most problems cycling ammunition.
My only gripe is that they are pricey as .22 ammo goes, but still not bad. If you're doing any serious shooting, like hunting, you may as well pay the extra money. A box of 100 pre-panic was still cheaper than a box of 50 anything in a higher caliber.
