The .338 Lapua Magnum (8.6×70mm or 8.58×70mm) is a Finnish rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. Due to its use in the War in Afghanistan and the Iraq War, the cartridge has become widely available.
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
Variants of the company's bolt-action rifles use .338 Lapua Magnum and .300 Winchester Magnum ammunition. Semi-automatic variants are available in 7.62 NATO, 5.56 NATO and .300 BLK. In September 2016, the company began selling the M1400, a squad-level .338 Lapua bolt-action rifle that can hit targets out to 1,400 yards (1,280 m).
Another method of determining trajectory and ballistic coefficient was developed and published by Wallace H. Coxe and Edgar Beugless of DuPont in 1936. This method is by shape comparison an logarithmic scale as drawn on 10 charts. The method estimates the ballistic coefficient related to the drag model of the Ingalls tables.
The PGM 338, also known as the PGM .338 LM (LM - Lapua Magnum) or PGM Mini-Hecate .338, is French sniper rifle from the early 1990s (being produced since 1993). [1] It uses the .338 Lapua Magnum (8.6×70mm) cartridge, which remains supersonic up to a range of 1200–1500 m depending on the exact ammunition type and environmental conditions.
For a typical .338 Lapua Magnum rifle for example, shooting standard 16.2 gram (250 gr) Lapua Scenar GB488 bullets at 905 m/s (2969 ft/s) muzzle velocity, field testing of the software should be done at ≈ 1200-1300 meters (1312-1422 yd) under International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m³). To check how ...
The 19.44 grams (300.0 gr) 8.59 mm (0.338 in) caliber Sierra HPBT MatchKing projectile was not available when the .338 Lapua Magnum was originally designed (it was optimized for shooting 16.2 g (250 gr) projectiles) and .338 Lapua Magnum cartridges intended for military use are generally loaded with shorter 16.2 g (250 gr) to 18.47 g (285 gr ...
Nosler Partition or even the 250gr partition the .338-06 can handle the largest North America game including moose and brown bear. Rifles chambered in .338-06 need not be as heavy as a .338 Winchester Magnum or other .338 magnums; therefore, .338-06 chambered rifles are desirable for mountain hunting or where excessive weight is an issue.
