RE: 8MM Mauser project
Just it once with one type of ammo doesn't mean that it is not accurate. Try a couple different types of ammo with it and see what shoots th best. While you have it taken apart have it cleaned really good. Those military surplus rifle can be realy sometimes. Take it to a gunsmith maybe he will know what to do. You could have the barrel free-floated but if you dont want to change it maybe not. I would look on the internet for a new stock. And alot of times the barrels in those guns are shot out.
