Bob thanks for the information. I am always interested in others expierences,as one is never to old to learn something new. I was in contact with my original guy that was going to make me the 2 bore today, and he has found someone to help with the heat treating that he needed on a few pieces of metal. So my project is not dead yet.It looks now like it may be completed in about 5 months. The barrel is 33" long and the total weight will be about 23 or 24 lbs. The bore diameter is a full 1.36" and it is a black powder muzzle loader.It will shoot a 3500 grain ball. The stock and barrel are complete now. Work on the under stock firing mechanism and trigger have been the hold up. This is not going to be a fancy gun, just something I feel the need to shoot. My Ken Owen 4 bore double is supposed to be completed by November. It has the full 1.052 bore diameter, 22" barrels and will weigh appx 26 to 27 lbs. It is like Safari Kids, except for 2" longer barrels and it is left handed and no fancy engraving. While I have not shot a 4 bore double or a 2 bore B.P. gun, I have shot my 700 nitro Saercy Double, my 600 Overkill and my 585 wells magnum quite a bit. I will work up cautiously on the 2 bore loads. I do not mind big recoil, but I don't want to have my ass knocked on the ground either. There is just something that intrigues me about the big bore rifles or (handguns 600 nitro, 50 alaskan, and 460 weatherby). I am sure that being crazy helps!
