The .338 Lapua Magnum cartridge was developed as a joint venture between the Finnish rifle manufacturer SAKO and the British rifle manufacturer Accuracy International, along with the Finnish ammunition manufacturer Lapua, or more officially Nammo Lapua Oy, which since 1998 is part of the Nordic Ammunition Group (Nammo).
The .338 Lapua Magnum case by itself has been based on the .416 Rigby. The .460 Weatherby Magnum has a case head diameter (0.580"/ 14,73mm) unique to the large Weatherby belted magnum cases. Few other cartridges use this case head size (or something close, like the .416 Rigby).
The commercially successful .338 Lapua Magnum cartridge has functioned as the parent case for the 7.62mm UKM, which is essentially a necked-down shortened version of the .338 Lapua Magnum. The .338 cartridge case was used for this since it has the capability to operate with high chamber pressures which, combined with smaller and hence lighter ...
The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior. A very high ballistic coefficient vehicle would lose velocity very slowly and would impact the Earth's surface at higher speeds. In contrast, a low ballistic coefficient vehicle would reach subsonic speeds before reaching the ground. [75]
The calculation assumes a flat-fire scenario (a situation where the shooting and target positions are at equal elevation), using British military custom high-pressure .338 Lapua Magnum cartridges, loaded with 16.2 g (250 gr) Lapua LockBase B408 bullets, fired at 936 m/s (3,071 ft/s) muzzle velocity [27] under the following on-site (average ...
The .338 Norma Magnum prior to C.I.P. certification had a shorter cartridge overall length (91.44 mm (3.60 in) compared to the cartridge overall length of the .338 Lapua Magnum (93.50 mm (3.681 in). The .338 Norma Magnum loaded with 19.44 g (300 gr) .338 caliber Sierra HPBT projectiles will have these projectile less deeply seated compared to ...
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 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.
