I seem to recall Selous 4 bore was a shortened Dutch fowler. The barrel was shortened to something like 24" or 26".
: I-too would hope for more weight than a 'fowler' might have. Perhaps it will have enough weight. The double barreled 4 bores weighed some 20 lbs. to 24 lbs. yet kicked horrendously - well over 200lb. recoil as tested by W.W. Greener. A .460 WTBY has some 86 pounds recoil for expample, and a .458 Winchester some 56 pounds recoil.
: .955" sounds a bit small, but then, a smoothbore requires a smaller ball than a rifle does. .955" is just over 6 bore which is around .92", I believe. Is a 4 bore not 1.1"? If so, I would think a ball 1.05" would allow a .030" thick patch which is very heavy denim, with .005" compression each side. This would be very easy to load and shoot. I would think a .955 ball too small (for a 1.1" bore), requiring a .073" thick patch just to reach each side.
: Is it possible, they are making a smaller, 5 bore instead? For all intents and purposes, it is much the same.
: Too many questions without having the gun in your hands- sorry, but, food for thought, just the same.
