I am new to this board, but have been on several others.AR and NitroExpress.com, and was doing a search on slug guns when I found this board and this thread. I too have been giving a lot of thought to doing some mods to a double shotgun as some of you here have, installing good sights and setting it up for slugs. How one would do the regulating, asuming the likely prospect that the gun will not be regulated for slugs to begin with, has been the sticking point. It seems to me from my looking around that there are a lot of shooters who want this type of gun, and very few who have actually regulated one. I am interested in others experiences and ideas, and would love to experiment with this idea. The most intriguing thing I have found was a post on NitroExpress.com that some of you may have seen in which someone described a Stevens(I think) that he acquired which, to be brief, had been regulated by removing material from the insides of the muzzles to move the points of impact of each barrel and apparently achieved a pretty decent grouping. Has anyone here heard of this? I am puzzled as to exactly how this would work, but some have indicated that it seems possible. I would be interested in hearing any thoughts on this idea.
