|AR-15 & Military Cartridge Section
In an effort to develop cartridges for forcible entry and other shorter range combat operations; many ideas have come up for
a cartridge that will disable a combatant without taking out the neighborhood with an over-powering caliber that works well
on the battlefield at more the 100 yards.
The idea was to use a shorter barrel version of the AR-15 platform with many smaller pistol calibers, or smaller rifle calibers
loaded to sub-sonic velocities.
There have been a few new calibers designed for this type of duty and the 338 Spectre is one of them, with a 300 grain
projectile traveling at below sonic speed.
The .338 Spectre is the brainchild of Mr. Marty ter Weeme of Teppo Jutsu Co LLC.
The cartridge has a wide array of applications, including small to medium game hunting, match target, suppressed sniper
shooting and forcible entry.
Like many new calibers, the .338 Spectre cartridge was developed specifically for the AR-15 family of gas-operated,
detachable-box magazine-fed firearms.
The cartridge is intended to fill the gap between traditional pistol caliber cartridges and existing rifle
cartridges used in this weapon system. It shares rim size with the new Remington 6.8 x 43mm SPC cartridge, allowing use of
OEM bolts in this caliber.
