I am ordering a 38 inch long 12 guage barrel. It has a 15 inch tapered octagon section and then goes to round. It is 1 1/8th at the breech. Is this too much barrel to use on a half stock shotgun type gun? Am I better off using a full stock? Any suggestions on what books or websites to look at, or even who to talk to about such a project? Is there a specific group that length would put it in? Is walnut more appropriate? I need info! I don't mind basically copying my Trapper, except in flint, but I don't know how that will look with the heavier and longer barrel. The Trapper has about a 5 inch octagon breech area and this barrel has 15 inches. That would take the octagon portion past the end of the trapper stock a few inches. Longer half stock or full stock?
