I got a 93 mauser that has a 243 win barrel on it. After learning of the potential for unsafe conditions, I parked it. It always shot like a champ, but why risk it. I learned to research THEN buy. This barrel is new, only few rounds thru it. If it fits a 93 action( 2lugs, cocks on close), would it fit on 98 action(1946 spanish mauser, 2lugs up front,one on rear and cocks on open)? Thanks
