[QUOTE="Bart B, post: 782656, member: 5302"] A good barrel will shoot 200 to 300 shots under 6 inches at 600 yards. At 100 yards, the group would be under 1/3rd inch. They don't foul enough to cause significant accuracy degradation until about 400 rounds. Lapping the bore out to smooth it up and lower the high points makes the bore and groove diameters a bit larger. Maybe enough to have less accuracy than before. [/QUOTE]
