You may want to contact the folks a Sharp Shooters Supply. They are Savage experts and sell lots of parts for them. They are also a gun smithing place for Savages. They have opened 223 size heads to 6mm PP. They also chamber rifle barrels as well as sell them. They may be able to do it for you or at least tell you if you can or not. Beware that the magazine may be the biggest obstacle to over come. You may have better luck finding a Remington 788 some where. They were not the best finished rifles in the world, but they shot very well. You could get them in 30-30 and 44 Mag with the usual 222, 223, 243, 308 among others. You might even be able to get a different 788 and buy parts to convert it over. Just some thoughts.
