My personal experience with a Caywood Type D, jug choke, and my associates' experience with other Caywood smoothbores has been good.
On the negative side I do not care for his outside-coned touch hole.
Locks spark very well, guns well made and attractive.
Rifles I dunno. Had a Southern Mountain rifle with a .45 cal Rayl barrel. Beautiful little rifle. Shot great at 25 yards but 8" groups at 50 yds. With enough powder I got that down to 4" but it was a very light rifle & started to be uncomfortable. I am into comfort. Yeah, I know, I don't know how to load, shoot, &c Nevertheless when I made rifles with, for example, Pa Keeler .50 cal 48" barrels I had no trouble sighting them in at 50 yards, with a modest load.
Caywood makes a great smoothbore. His delivery is on the long side.
