What do i need to know before trying this? Will all models savage fit? I have a 110 in 270win. and i would just like to try this. I know to used a cartridge that is .473". Can i put a short cartridge like a 22-250 on my 110??Are the ER Shaw barrel kits any good? or should i just buy a barrel, a wrench,etc? Is the Stevens barrels i read about the same, do they work on a savage?
