U.S. Military . Unlike most military sniper rifles, the Model 300 was purpose-built for the military, not reworked from an existing civilian rifle - another such sniper rifle was the Soviet SVD. Though not adopted in large numbers by the U.S., the weapon served as a testbed for new sniper ammunition. The cartridge originally used, the8.58 x 71 mm , was eventually developed by the Lapua-Nammo Oy company inFinland into the.338 Lapua Magnum .The Model 300 was a bolt-action, magazine-fed weapon, featuring a steel receiver with a rotating bolt. The bolt had 3 long lugs which locked into the receiver walls. The weapon could use one of two cartridges: the
7.62 x 51 mm NATO and the 8.58 x 71 mm. Switching between calibers was relatively simple, requiring that only the barrel and bolt head be replaced. The Model 300 featured a detachable scope mount, heavy precision barrel, a folding bipod, a fully adjustable trigger and could be disassembled for ease of carry and storage.External links
