Mike,
I agree with the Capt but if you feel that it is not safe to fire the piece then don't.
I have an old Winchester Model 1904 22 bolt action single shot rifle. BBL markings are 22 short,long and extra long.
Obviously an old piece and I do not want to take a chance in firing modern HV ammo in it so just on the occasion shoot CCB caps in it.
