Just be aware that some blowback or delayed blowback 22MAG rimfire actions can permit firing out of battery (with sometimes ugly consequences) if a cartridge has not quite fully chambered due to a dirty chamber or deformed (severely dented) cartridge case. Shouldn’t be any problem if the gun is kept reasonably clean and ammo is even casually inspected routinely while loading magazines.
I once owned a Kimber .17M2 1911 conversion unit. Very accurate, but it would fire slightly out of battery as well, or possibly opened a bit early, bulging the case just ahead of the rim. Never had a rupture, but it was disconcerting considering the pressures involved. Sold the pistol itself and then later the unit as it was my sole 1911.
Wish I had all that older Mach 2 ammo back!
