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]
In modern bullets, such as the 7.62 illustrated here, the cannelure is pressed into the circumference of the bullet to provide a strong purchase for the mouth of the cartridge case when it is crimped onto that cannelure. This is done to prevent the bullet from moving either forward or backward in the case. [4] [5]
An open single-cavity bullet mold and a closed two-cavity mold. 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.
CCI was founded by Dick Speer (brother of Vernon Speer, who founded Speer Bullets) in the early 1950s. Arvid Nelson was a partner in the business. The firm's first shipment was part of a defense contract to make primers using chlorate FA-70. CCI later moved on to much safer formulas for sporting ammunition.

Handgun propellants may reach peak pressure before the bullet leaves the cartridge case, while rifle propellants may move a bullet several inches before reaching peak pressure. [4]: 125 The motion and behavior characteristics of projectiles while under the influence of the gases produced by the propellant is known as internal ballistics. [13]
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

Following a logic of increasing performance through size, they had evolved from small handguns to giant wrought-iron or cast-bronze bombards within a span of just several decades. [1] Iron balls and shot: By the 16th century, however, a general switch from stone balls to smaller, but much more effective iron projectiles was in full swing.
