If you over charge the rounds beyound book values neglect the gun letting the bore rust up or store nails in the chamber of course it will explode.
Model 70's are pretty strong.
My preference is the classic control feed design over the pushfeed design.
Never been a huge fan of push feed bolt guns.
"Gun control: The theory that a woman found dead in an alley, raped and strangled with her panty hose, is somehow morally superior to a woman explaining to police how her attacker got that fatal bullet wound." L. Neil Smith
The problem with being stupid is you cannot simply decide to stop doing dumb things...
