We got a nice, tight 4 inch pattern. Improved Cylinder has a minimal restriction. [12] Dyer claimed that White's patent litigation during the American Civil War served as "an inconvenience and embarrassment" to Union forces for the "inability of manufacturers to use this patent". Rifled slugs can be designed to deform through the narrower choke, but will lose both power and accuracy relative to a cylinder or improved cylinder choke. White was born in Williamstown, Vermont in 1818. White sued them, but not until after they had made 7500 revolvers. A ' Foster slug , invented by Karl M. Foster in 1931, and patented in 1947 ( U.S. Patent 2,414,863 ) is a type of shotgun slug designed to be fired through a smoothbore shotgun barrel, even though it commonly labeled as a "rifled" slug. He assembled these parts into a single bored-through cylinder that would fit in a Colt revolver.[1]. Then at 12 yards with the rifled barrel. The "rifled" slug, used in smooth-bore shotguns, has rifling or ribs on the slug. #3 will usually go through one lung. If it's the latter, it may not swing as well, but it would be perfectly normal to shoot shot through it. Improved Cylinder = Short-range choke that delivers wider shot patterns for game within 35 yard Skeet = Produces 60% pattern in 30" circle at 25 yards Full = Delivers tight, well-placed shot patterns when shooting between 45-55 yards Light Modified = Versatile Choke that delivers wider shot pattern for shooting at 20-40 yards In 1863, White had another of his patents, US Patent 12649, which was for a front-loaded gun, reissued with a breech-loading feature.

We will shoot several different buckshot loads through an Improved Cylinder Choke and then through a Full Choke, and see what happens to the size of the patterns. The patent drawings imply that a percussion cap would have had to be applied to the single nipple for each shot, so it would have been far slower than the existing cap-&-ball revolvers.

This gave White two patents of the same date for the same invention. It can even be fired through barrels with full chokes, however best results will come from an unchoked (cylinder bore) shotgun barrel.
