A while back, someone stated that enlarging a 20g bore over the standard by a certain amount, had a very beneficial effect on the pattern.

I'm contemplating backboring for a few reasons. I'd like to lighten the gun a little in the front to shift the balance back a bit, and lighten it. I'd also be interested in optimizing the pattern.

Can any of you that have experience in overboring 20ga's weigh in?

BTW, who would be best qualified to do the work?
