I had a Remington 700 varmint special in 6 mm that had chatter marks and this rifle was my first one that would shoot 3 shot .250 groups after a lot of fiddling around with loads. The catch was you had to clean it every 15 or 20 rounds with sweets 7.62 solvent or it would copper foul quite badly. Won a lot of turkey shoots with that rifle and shot a truck load of coyotes. That barrel is long shot out and gone now and I have to admit I do not miss the excessive cleaning it took.
