Ammunition Cartridge Size Comparison Chart - Pistol, Rifle & Shotgun Rounds #9055 (License: Personal Use)

This diagram displays six representative firearm cartridges arranged left to right by increasing size: .22 LR rimfire, 9mm Luger, .45 ACP, 5.56×45mm NATO, .308 Winchester, and 12-gauge shotgun shell. Each is rendered as a clean grayscale silhouette to emphasize structural differences-such as bottlenecked rifle cases versus straight-walled pistol and shotgun shells-and relative proportions critical for understanding chambering compatibility and ballistics.
