A cast bullet is made by allowing molten metal to solidify in a mold. Most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity. Most commercial bullet manufacturers use swaging in preference to casting, but bullet ...
Two-headed bullets (angels) were similar but made of two halves of a ball rather than two balls. [1] Canister shot An anti-personnel projectile which included many small iron round shot or lead musket balls in a metal can, which broke up when fired, scattering the shot throughout the enemy personnel, like a large shotgun. Shrapnel or spherical ...
A typical bullet would consist of soft lead from 150 to 250 grains in weight with a black powder appropriate lubricant in the groove(s). Gallery loads using a 0.454" diameter 141 grain lead round ball may also be suitable for some applications. Crimping the case around the round ball may be necessary to prevent ball movement during recoil.
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball.
Use of shot towers replaced earlier techniques of casting shot in moulds, which was expensive, or of dripping molten lead into water barrels, which produced insufficiently spherical balls. Large shot which could not be made by the shot tower was made by tumbling pieces of cut lead sheet in a barrel until round. [6]
The subsonic round is originally designed to have an optimistic effective lethal range of 400 to 530 meters and a maximum penetration of up to 10 mm of steel. Like the 5.45×39mm cartridge, the 9×39mm SP-5 features an air pocket in the tip, which increases its tendency to yaw or "keyhole" upon impact, thus increasing soft tissue damage in ...
This worked well for low-speed bullets, fired at velocities of less than 450 m/s (1,475 ft/s). For slightly higher-speed bullets fired in modern firearms, a harder alloy of lead and tin or typesetter's lead (used to mold linotype) works very well. For even higher-speed bullet use, jacketed lead bullets are used.
The size of the lead shot that is produced is determined by the diameter of the orifice used to drip the lead, ranging from approximately 0.018 inches (0.46 mm) for #9 lead shot to about 0.025 inches (0.64 mm) for #6 or #7.0 shot, while also depending on the specific lead alloy that is used.
