Boom, maby, the rifle you are talking about uses only a staked bolt handle to hold the bolt shut, not real strong. Who ever rechambered it should be sentenced to firing 500 rounds out of it with out shooting glasses. I am a gunsmith and would never consider that job as safe. Hang it on the wall or do somthing with it other then shoot it!!!!!!!!!!!!!! You know, it is sad but there are people out there doing stuff like that and ruining guns all because either they are ignorant or don' t care. When in doubt check with some one who knows!!!!
