measures .875 at the receiver end . I'd like to build a bolt action handgun chambered ib .222 Rem , which has a cartridge base diameter of .378 , leaving just a bit over .250 wall thickness in the chamber area . The receiver will surround part of the chamber area , but not all . I'm thinking this is a bit thin for the pressures involved ... Is it ? If so , can I press fit a sleeve over the portion of the barrel that needs more strength ? Or should I be looking at something smaller , maybe .22
first time I saw a Remington XP100 ... and the barrel was free .
