Don't shoot LR in a Magnum rimfire cylinder though. Even though both are .22 caliber there is a difference in the design of the magnum case which will make the LR case fit loosely in a .22 mag chamber. .22 mag bullets are seated inside the magnum case, whereas .22 LR bullets have an extension on the back of the bullet that allows the bullet to seat in the LR case. Compare the two and you will see a .22 LR bullet will be flush with the case, whereas the .22 mag bullet seats inside the case like most normal ammunition. I forget the terminology but a .22 mag case will mic out slightly larger in diameter than a .22 LR case. It won't blow up in your face if you do it but its not recommended to shoot .22 LR out of a .22 Mag.
