Lead shot is still the best ballistic performer, but environmental restrictions on the use of lead, especially with waterfowl, require steel, bismuth, or tungsten composites. Steel, being significantly less dense than lead, requires larger shot sizes, but is a good choice when lead is not legal and cost is a consideration.
The .460 cartridge achieves high velocities by combining light-for-caliber bullets, a large case capacity, and the high chamber pressures (65,000 psi maximum) typical of magnum rifle cartridges. At the same time, the recoil when shooting .45 Colt ammunition out of the Smith & Wesson Model 460 is comparable to recoil from a 9mm or .380 load, due ...
The Marmot is based on the .220 Swift with improved characteristics such as steeper sides and shoulder angle, but is not improved in the sense that you cannot fire form factory ammunition in its chamber. Performance with a 50-grain (3.2 g) bullet is approximately 3,875 ft/s (1,181 m/s) and with a 55-grain (3.6 g) bullet is approximately 3,755 ...
