Could you be more specific, and perhaps provide a reference? Paul Mauser's group was pretty fussy about sighting through the new barrels, and bending them a little here and there to make sure their bores were perfectly straight. The WWII records on the M1 Garand talk of using a bore scope to adjust the adjustible iron sights. The WWII records on the M1 Carbine talk of the same technique.
