Pickt up a 6br barrel for one of the old Js a while back from EBCO. I have only fireformed the 100 rounds of brass for it so far but it seams to be a fair barrel. The threads seamed to be a little small as it fit very loose in the action till I tightened up the nut???? The barrel is a lot easier to clean than the factory Savage barrels but has yet to outshoot them( to be fair though I have not put it on a bench to ring it out to its fullest!).
