The industry change to steel shot, arising from the US and Canadian Federal bans on using lead shotshells while hunting migratory wildfowl, has also affected reloading shotshells, as the shot bar and powder bushing required on a dedicated shotshell press also must be changed for each hull type reloaded, and are different than what would be used ...
Bags of lead shot, for sale at on Sunday, Nov. 12, 2023, for sale at $56.99 in the Atterbury Shooting Complex in Edinburgh. Lead is commonly used in shotgun shells and bullet rounds found here.
A shot tower is a tower designed for the production of small-diameter shot balls by free fall of molten lead, which is then caught in a water basin. The shot is primarily used for projectiles in shotguns , and for ballast , radiation shielding , and other applications for which small lead balls are useful.
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 unround shot was either re-processed in another attempt to make round shot using the shot tower again, or used for applications which did not require round shot (e.g., split shot for fishing). [1] The hardness of lead shot is controlled through adding variable amounts of tin, antimony and arsenic, forming alloys. [1]
In metallic cartridges, peak pressure can vary based on propellant used, primers used, charge weight, projectile type, projectile seating depth, neck tension, chamber throat/lead parameters. In shotshells, the primary factors are charge weight, projectile weight, wad type, hull construction, and crimp quality.
Shot, small and round and delivered without spin, is ballistically inefficient. As the shot leaves the barrel it begins to disperse in the air. The resulting cloud of pellets is known as the shot pattern, or shotgun shot spread. The ideal pattern would be a circle with an even distribution of shot throughout, with a density sufficient to ensure ...
Most non-toxic shot shells produce higher chamber pressures than lead shot and can severely damage these older shotguns and as a rule of thumb, use a more open choke than one would for lead shells. An example would be an improved cylinder choke will perform like a modified choke when shooting steel or tungsten shells.
