Al,
Have seen things even worse in factory barrels. Probably mentioned one long ago in one of these threads: A major manufacturer's .300 Winchester Magnum barrel that had the lands totally missing about 1-1/2" from the the muzzle, probably due to reamer malfunction. The rifle wouldn't group better than 2" at 100 with any ammo until it was shortened enough to remove that "gap," and recrowned.
