Only with single barrel low value repeaters, I took off about a 8th of an at a time until I got the pattern I wanted, then filed the cut barrel square. The exception was a Boito (SP) SxS my Son wanted to use for a truck gun. The barrels would center patterns 10 inches apart at 20 yards afterwards just as they did before.

I would never cut a halfway decent gun, I promise.

Mine's a tale that can't be told, my freedom I hold dear.
