You got some kind of craving to shoot surplus ammo (as in "cheap, cheap, cheap?" --I have that problem myself) or you want a light, unusual rifle easy as possible? Otherwise, re barrel to a member of the .22/250 family. That .250 Savage is hard to beat for accuracy and soft recoil.
OR ...The 7.62 x 39 has a case capacity approximately that of the .30/30 WCF. Works at higher pressures... Etc. Point, the .225 winchester case is the old .30/30, almost, with a rim for the .473 bolt face a .22/250 uses. This gives you all the old .30/30 Imp cartridges and feeding thru a bolt action. .219 Zipper. Zipper Improved. .219 Don Wasp. 6mm Wasp. .25/35. 7 Waters. .30/30 Imp. You just have to "make" the case with the .225 Brass. And in a bolt action, accuracy...
You might find a bolt for the 6.8 that would fit your gun. Then you got the magazine to rework. Always something, but if you are having fun. LUCK.
