Ammunition Cartridge Size Comparison Chart - Pistol, Rifle & Shotgun Rounds #1772038 (License: Personal Use)

This schematic shows six representative firearm cartridges arranged in ascending order of overall length and diameter: a .22 Long Rifle rimfire round, a 9mm Luger, a .45 ACP, a 5.56×45mm NATO rifle cartridge, a standard 12-gauge shotgun shell (hull only), and a 12-gauge slug shell with full-length projectile. The silhouettes highlight key structural differences-rimfire vs. centerfire primers, bottlenecked rifle cases, straight-walled pistol cases, and the distinct proportions of shotgun loads.
