Yes, you can shoot .22 Mini-Mag ammunition in a rifle chambered for .22 LR, as .22 Mini-Mag is a type of .22 LR ammunition. However, it's important to ensure that your rifle is in good condition and properly maintained. While the Mini-Mag is a high-velocity round, it should function correctly in most .22 LR firearms. Always consult your firearm's manual or manufacturer for specific recommendations.
IF the revolver is marked ".22 LR" yes. If it is marked ".22 WMR" or .22 Mag" or " .22 WRF", then NO.
