Navy SEAL Sniper

Most Navy seals use the AWM(Artic Warfare Magnum) due to its extream accuracy at long ranges and its .338 Lupa Magnum rounds. The .338 Lupa magnum rounds are as compact as rifle rounds but have greater power and accuracy than .50 cal rounds.

The AWM in the .338 Lapua Magnum calibre was designed as a dedicated long range sniper rifle combining the manoeuvrability of rifles chambered in 7.62 x 51 mm NATO with the greater power and range of the .50 BMG cartridge.

Compared to most .50 calibre rifles, the AWSM offers considerably less rifle weight, recoil, muzzle flash, smoke and report. Although the .338 Lapua Magnum delivers less energy to the target compared with the .50 BMG, both cartridges have similar trajectories, resistance to wind drift and penetration, while the .338 Lapua Magnum unquestionably outperforms the 7.62 x 51 mm NATO, especially at ranges beyond 800 m. AWSM rifles in .338 Lapua Magnum can also be deployed against unarmoured hard targets, including armoured glass.

The AWSM is fitted with a stainless steel, fluted, 686 mm (27") barrel, which research has found to be the best compromise between velocity and precision on the one hand, and weight and length on the other. A non-traditional 279.4 mm (1 in 11 inch) right-hand twist rate was selected to optimize the rifle for firing 16.2 up to 19.44 gram (250 up to 300 grain) .338-calibre very-low-drag bullets. Whether this twist rate is adequate to stabilize 19.44 gram gram (300 grain) very-low-drag bullets in dense air encountered in Arctic sea level environments is questionable. The bullet manufacturer Sierra advises a tighter 254 mm (1 in 10 inch) twist rate for its 19.44 gram (300 grain) .338-calibre HPBT MatchKing bullet.

A problem with AWSM rifles is that .338 Lapua Magnum cartridges loaded to the C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) maximum allowed overall length of 93.50 mm (3.681 in) do not function properly due to a lack of internal magazine length. The reason for this problem is that the AWSM bolt-action is not specifically designed for the fat and long .338 Lapua Magnum cartridge. Because of this, ammunition manufacturers produce .338 Lapua Magnum cartridges that are loaded short enough (≈ 91.44 mm (3.600 in)) to fit in the AWSM magazines. As long as .338 Lapua Magnum cartridges that will fit in the magazins are used, the AWSM rifles can be used as repeating rifles instead of single shot rifles. Ammunition types currently (2007) available for the .338 Lapua Magnum are FMJ, hollow point, Armour Piercing (AP) and Armour Piercing Incendiary (API).

Frickin' Awesome. What's with the spelling mistakes though? Goes from AWM to AWSM (awesome?) and other things.

lol the AWM is the basic one. The AWSM(Arctic Warfare Super Magnum) is custom and more advanced with stainless steel barrel and capability to fire .300 winchester, .338 lupa magum, and the good old .50 cal rounds. This is so the gun can be fired with more than one type of ammo making it easier to locate ammunition. It won't work as well, but if you have no ammo you can use turret .50 cal rounds for the sniper. As for the spelling mistakes I couldn't copy and paste cause the site had the copy right thingy. So I typed it quickly.

Oh okay cool. Thank's for clarifying.
