The Savage Edge looks to me like the standard 110 action except it has a knoch mill into the frount of the action. The knoch is there because there is no recoil lug on the barrel and they have it molded into the stock. As for rebarreling it would be the same as any other savage action, but if you want to change stock you would have to put a recoil lug on the barrel. I bought on in 22-250 at a gun show awhile back and about fell over when I saw their recoil system, but the rifle is a tack driver so I guess it works. Also if you rebarrel to a round with a different case head you would have to change the bolt face on the bolt, but that is not hard to do eather.
