Its a very poorly designed copy of the Savage. There was a post on another forum of a 4x4 that took out some guys teeth, not sure what happened to the rifle as far as blowing up is concerned. Its cross pin, that holds the bolt head on, broke and the lugs were not engaged when the trigger was pulled. The soldered on bolt handle has no slot to fit into either and it came back into the shooters face at a high rate of speed.
Stick with the Savage/Stevens.
