Most manual action .22 magnums will work OK with the WRF. It has been a long time but if memory serves there is a tiny difference in diameter and the magnum case is longer but I know I have fired WRF in magnum rifles with no problem
Of course the WRF will not have enough power to operate a semi-auto.
except for the brand spankin new keltec pistol, there is no such thing as a 22wmr semi auto. IIRC.
