I have just returned from my club after firing this rifle for regulation. Two weeks ago I was not happy with the way the left barrel was spreading its shots. I spent some time with the two muzzle-crowning tools shown in the one photo, and three different grades of grinding/polishing compound. I also heated and adjusted the barrels using my new regulation rig (shown elsewhere). The results are startling, as you can see. I experienced the same dramatic improvement after re-crowning one barrel of a friend's .375 Fl. Mag. double a few weeks ago. Something to remember if you encounter a similar problem. I'm a happy camper today! Time to tear her down and start polishing and rust bluing!
