Dean Harris of Skeet's Gun Shop in Tahlequah, OK has a different method of moving patterns to point of aim. He uses a Cratex bob on a long mandrel to reach from the muzzle back to the "transition area", as he calls it, where the bore first begins to constrict into the choke area. He removes metal there, in his own manner, and shoots. This is continued until the pattern has been moved the needed amount, if possible. He has had some phenomenal results.
He has a Sterly 20 of mine right now. One barrel was cross firing badly ............ very badly.
