Judson,

Contratulations on your project. As Marrakai pointed out in one of his comments, most of what has been written here is a collection of ideas and opinions, some good and some not so good, but few experiences like yours. It is good to see great positive results from risky projects like building a double.
Another friend told about a successfull deer hunt using his home made 12 bore rifle, and it was a pleasure to read about. His project gun is also another very good example of a great "home-made" gun.
Speaking for myself, I am on the works of building a double too, on a Beretta action. I hope I will have the gun ready for test fire in the next few weeks (progress is being slow...). I hope it will look so good as yours. Again, it is being great to know all the details of your project.

Fred
