yes, glass bedding these rifles does increase the accuracy. I've bedded three or so, 2 k98's and a chilean 7mm 93. Honestly, with a stock barrel, it was almost worthless. In the 7mm's case, it made the accuracy worse (some hubub about a pressure point at the end of the barrel for the mil stock). Great fun to bed a rifle, if you've got the time to kill.
And Shenandoah is right on with the milsurp corrosive ammo. I used to have some turkish 8mm surplus a long time ago that was absolute garbage, and dirty as all hell. They were almost giving it away...
If you REALLY want to get horny with it, there's aftermarket .308 barrels that used to be available for the action. Bull barrels, Hart I believe. They were milsurp from UK sniper rifle builds. My friend mounted it up to the mauser action and I shot it out at 500? I think?? Hit paper and grouped at about 5". That was with commercial ammo and no practice. If hand loaded, and practiced, and perhaps restocked, it would have been a 1000 yd possibility.
SO yeah, if you want to start finger-banging that thing and throwing money and parts at it, three years later you'll sell it when you need money for an MRI.
If you like to shoot it, keep it as is and enjoy it.
