Don't shoot X bullets from a nice rifle like that. Just do a search here on the bullet with the worst accuracy. If you had a screw machine "lump" there then go ahead and foul it up but not a classic that you clean from the muzzle!
IS there any reason why a plain, ol' .308 Win. load would not work in an M88 just as well as any other rifle that has a set of up-front locking lugs?? What difference does the type of bullet make here?
