I have a 12 gauge franchi I-12, and it doesn't appear to be aligned exactly right.

I have switched the shims, with no success.

I have heard about a process where a gunsmith can correct this by putting a slight bend in the barrel to make it straighter or to correct the prblem.

Has anyone done this before? What was your cost? Is it better to just get a new barrel?

whenever I go to shoot clays, I outperform the franchi with my remington 870 em 20 gauge.
