I just wanted to clarify this post. When I sent these barrels to Mike Orlen (who does excellent work) I asked for Thin Wall setups in all of them. Some were double barrels and the one in question an 870. When I talked to Mike (finally reached him after the initial post), he explained that the Thin Wall setups are best in the Double barreled guns and the regular, thicker walled choke tubes are best in the single barreled guns because it is apparently better to have the tube be as thick-walled as possible.
I don't really understand why it matters which part of the setup is thicker-walled--either the barrel or the choke tube. Either way, the thickness of the two combined would be the same, at least it seems to me.
Mike is a very good barrel guy. His turnaround on these barrels was slow but he has had some health issues and hopefully that is behind him. Gil
