i have a savage 110 in .243 and am wanting to insatll an aftermarket barrel but am also looking to upgrade to a newer short action savage 10 and was wondering if the barrel will match up to both the 110 and the 10 actions ? also can some bodt tell me what the differences are between the savage models like the 10 11 12 etc? are they the same actions with different components or do the actions vary as well?
