.308-caliber precision rifle, Bolt-action or semi-automatic precision rifle class, Infantry WeaponsInfantry Weapons.308-caliber precision rifleBolt-action or semi-automatic precision rifle class.308-caliber precision rifles are scoped small arms chambered in .308 Winchester, 7.62x51mm NATO, or closely related .30-caliber service cartridges, depending on the model and markings. The class spans law-enforcement, military, sporting, and long-range precision roles. In the 2022 Haitian Gang Conflict entry, the sourcing supports illicit trafficking of .308 rifles into Haiti and gang-linked demand for higher-powered rifles, but it does not identify a specific model or prove a documented firing incident.
45 Automatic (45 Auto), Rimless centerfire pistol cartridge, MunitionsMunitions45 Automatic (45 Auto)Rimless centerfire pistol cartridge45 Automatic (45 Auto) is SAAMI's recognized name for the .45 ACP cartridge developed around John Browning and Colt's early self-loading pistol work and adopted by the U.S. Army with the Model 1911 pistol. This relationship-only page covers the cartridge as a standardized handgun and submachine-gun round, with SAAMI and C.I.P. dimensions, U.S. military ball-cartridge context, current commercial loads, and a sourced compatibility link to the Glock 21 family.

C.I.P. lists Finland as the country of origin, while Lapua and Nammo sources show current tactical, target, armor-piercing, hunting, and special-purpose load families. The linked rifle relationships stay limited to cataloged weapons whose sources document .338 Lapua chambering.
.300 Norma Magnum, Long-range centerfire rifle cartridge, MunitionsMunitions.300 Norma MagnumLong-range centerfire rifle cartridge.300 Norma Magnum is a Swedish-origin long-range centerfire rifle cartridge in the Norma Magnum family. Norma presents the caliber as a modern precision cartridge tied to its earlier .308 Norma Mag lineage, while C.I.P. lists Sweden as country of origin and SAAMI later accepted the 300 Norma Magnum for standardization. The record links documented chambered rifles such as the Barrett MRAD / MK22 and PGW Timberwolf Gen 3 without turning those relationships into conflict-use claims.
