I agree, forget the liner option. I would rebarrel with a 12 twist 30 cal barrel and chamber it for 308. If you get the right size barrel (like a No 7 Douglas) get your gunsmith to take barrel down to .800" diameter 10" infront of action and mount a Weaver 92A scope base on it and install a NC Star 2-7X pistol scope and you are good for 600 yards easy. That is cheapest way I know to mount scope on mauser and also allows you to use the stripper clip slot reloading capability.
