2 Bore Jones Underlever Black Powder Cartridge Side by Side Rifle “The Double Deuce” Part 1
Last June I took the 2 Bore Jones Underlever Black Powder Cartridge Rifle to the NMLRA Spring Shoot, along the way I stopped off at a customer’s house to pick up a 2 Bore Muzzleloader I had built. While I was there he had the opportunity to handle the cartridge rifle, and decided to order one. Somewhere along the way as we discussed his build he decided he would rather have a double rifle, so this is the beginning of the documentation of the project.
I will be documenting this build in pictures, text and some video’s. I don’t have a youtube account that allow me to post more than 15 minutes at a time, so the videos will be limited to filling in details that would be hard to explain in written form.
