Lead could be cast in a ladle over a wood fire used for cooking or home heating, while casting iron required higher temperatures. Greater density of lead allowed lead bullets to retain velocity and energy better than iron bullets of the same weight and initial firing velocity. [2] Minié balls of the mid-19th century could be either cast or swaged.
Cast bullets as cast (left), with gas check (center) and lubricated (right). A gas check is a gasket type component of firearms ammunition. Gas checks are used when non-jacketed bullets are used in high pressure cartridges. The use of a gas check inhibits the buildup of lead in the barrel and improves accuracy. [1]
Though the higher velocity loads would be destructive for small game use, the handloader can run heavier cast lead bullets such as the 85 gr. LRNFP at more sedate velocities around 1,000-1,200 FPS to anchor game with much more authority than the .22 Long Rifle, yet not destroy meat.
The .351 SL cartridge used an unusual bullet diameter of .351 instead of the .357 or .358 more commonly used in .35-caliber rifle cartridges. [6] Most ammunition available today for the .351 SL is produced by a few boutique manufacturers, often using either cast lead bullets or copper-plated bullets or, occasionally, .358 jacketed bullets ...
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
Full factory velocity handloads when assembled using hard-cast, gas-checked bullets of .432 in diameter rival accuracy of any jacketed ammunition for this cartridge. [ 7 ] Three years after the introduction of the .444 Marlin, Hornady introduced a new, heavier, 265-grain (17.2 g) .430 inches (10.9 mm) bullet created specifically for use in this ...

It was also small bore (7.5 and 8 mm) and it is the precursor of the 8 mm Lebel bullet adopted for the smokeless powder ammunition of the Lebel Model 1886 rifle. The surface of lead bullets fired at high velocity may melt from the hot gases behind and friction within the bore.
