Several firearms manufacturers chamber rifles for the .300 Norma Magnum cartridge, a relatively new round designed for long-range precision shooting. These manufacturers range from large, well-established companies to smaller custom rifle builders. Typically, rifles chambered in this cartridge are bolt-action designs, built for accuracy and durability, and often feature heavy barrels and specialized stocks.
The popularity of this specific cartridge stems from its ability to deliver heavy bullets at high velocities, resulting in exceptional long-range performance. This makes it a favored choice among long-range target shooters and some military and law enforcement snipers. Its development addressed perceived shortcomings of other long-range cartridges, leading to its adoption by competitive shooters and specialized military units. This growing demand has subsequently driven a wider availability of rifles specifically designed for this cartridge.
