The commercially successful .338 Lapua Magnum cartridge has functioned as the parent case for the .300 Lapua Magnum, which is essentially a necked-down 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 ...
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 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]
.338 Lapua Mag Another consideration of the Whisper family design is that all of the cartridges are based on existing cases that utilize common case head dimensions. This allows rifles with common bolt face dimensions to be converted to a Whisper cartridge fairly easily, often requiring only the rifle's action to be re-barreled.
The LWMMG can be mounted on an M240 mount and costs about the same. While the company is satisfied with the shorter .338NM cartridge's performance, the gun could easily be converted to .338 Lapua Magnum. The gun's short recoil operating system causes the barrel to reciprocate, similar to the M2 machine gun. This combined with a gas system to ...
The MG 338 was planned to have a similar weight to the M240 but, with the .338 Norma Mag, deliver terminal effects on targets similar to that of the .50 BMG. [11] [12] Programs for acquisition of .338 Norma Mag ammunition began in 2018. [13] [14] Acquisition of the weapon system began in 2019. [15] The MG 338 was first unveiled at AUSA 2018. [16]
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.
The .338 Xtreme possesses a full 50% more case capacity than a .338 Lapua Magnum cartridge, but it drives a projectile with a claimed G1 ballistic coefficient of 0.825 of like mass at only 10–12% more velocity from a similar length barrel when measured at the muzzle.
