Common Lead Round Nose (LRN) Calibers

• .22 LR:Arguably one of the most popular calibers in existence, the .22 Long Rifle made its debut in 1887. Introduced a year after the introduction of viable smokeless powder, the .22 Long Rifle quickly took advantage of the benefits of the newer type of propellant. While .22 Short and .22 Long loadings initially used black powder, the smokeless powder utilized by firearms after 1886 made for a more efficient and effective propellant. In a departure from the .22 Long, the .22 Long Rifle is able to reliably function in semi-automatic firearms. Semi-automatic pistols and rifles in .22 Long Rifle are some of the most common firearms owned by shooters in the United States. A firearm in .22 Long Rifle is a “first gun” for many new shooters and is an excellent caliber to learn with.
• .38 Special:The .38 Special cartridge was developed by Smith & Wesson in 1898 and has a long history as a reliable round for law enforcement, self-defense, and target shooting. Known for its manageable recoil and effectiveness, it became one of the most widely used revolver cartridges in the 20th century. Even today, it remains a staple among revolver enthusiasts and is commonly found in both new and vintage handguns.
• 9mm:The 9mm Luger cartridge is easily the most common handgun round in common use. The caliber goes by many names, often being referred to as 9mm NATO, 9mm Parabellum, 9x19mm, or just generically “9mm”. The cartridge’s origins can be traced back to the early 20th century and is the brainchild of Georg Luger. Originally found in firearms such as the Borchardt C-93 and the P-08 Luger pistol, the round has become a common chambering for handguns in civilian and military use from the 20th century onward. Firearms such as pistols and submachine guns in 9mm Luger have commonly been used by military and law enforcement personnel across the globe, leading to the round establishing a reputation for being a reliable service cartridge.
• .45 ACP:The .45 ACP, or .45 Automatic Colt Pistol, cartridge is the brainchild of prolific firearm designer John Moses Browning. Originally developed in 1904, the cartridge is closely associated with the 1911 pistol, an iconic service pistol chambered in .45 ACP. Beyond its use in handguns, the cartridge is well-known for being used in submachine guns such as the Thompson and M3 “Grease Gun.” The .45 ACP notably served the United States and allied nations throughout both World Wars and in many of the conflicts throughout the 20th century.
• .32 ACP:Like the name suggests, the .32 Automatic Colt Pistol, or .32 ACP was also developed by John Moses Browning. Introduced in 1899, the cartridge is commonly referred to as .32 Auto. The cartridge helped legitimize the new-at-the-time concept of a semi-automatic handgun. The cartridge debuted alongside the FN Browning M1900 semi-automatic handgun. Notably, this pistol was the first to make use of a slide. Pistols and submachine guns have been chambered in this cartridge. Notable examples include the legendary Walther PPK and the Czechoslovak vz. 61 submachine gun. Like the .25 ACP, the .32 ACP was also incredibly popular in Europe during the height of its popularity. In metric nomenclature, the cartridge is known as the 7.65 Browning.
