CEP is not a good measure of accuracy when this distribution behavior is not met. Munitions may also have larger standard deviation of range errors than the standard deviation of azimuth (deflection) errors, resulting in an elliptical confidence region. Munition samples may not be exactly on target, that is, the mean vector will not be (0,0).
One of the first caseless firearm and ammunition systems produced was made by Daisy, the airgun maker, in 1968. The Daisy V/L rifle uses a .22 caliber (5.5 mm) low-powered external-propellant caseless round with no primer. The rifle was basically a spring-piston air rifle, but when used with the V/L ammunition the energy from the compression of ...
One notable exception to this is the .50 BMG cartridge; competition shooters often fire high-precision lathe-turned bullets made from harder brass, bronze, or steel in this caliber, and the 4140 steel will stand up to this better than stainless. [37]
Its shot-to-shot variation is expected to be better than 1 minute of angle (MOA) with match ammunition. This level of accuracy is only average compared to most modern bolt action sniper rifles, but is still exceptional for a semi-automatic rifle and at one time was claimed to be "one of the most accurate semi-automatic sniper rifles in the ...
The Pike is a precision-guided mini-missile [1] or grenade munition designed by Raytheon.It is a 40 mm guided munition that can be fired from the barrel of a Heckler & Koch M320 Grenade Launcher Module and FN Enhanced Grenade Launching Module (EGLM) like a standard 40mm grenade, but is powered by a rocket motor to propel it 2,000 m (2,200 yd; 1.2 mi) to give infantrymen improved extended-range ...
One kind of smart bullet is a projectile that is capable of changing its course during flight. One use of this would be to enable soldiers to stay behind protective cover and shoot around corners. One implementation uses a spoiler and micro gyro to control the bullet.
Manufacturing match grade ammunition and other parts requires extremely tight tolerances and quality control. It is not unusual for match-grade ammunition and components to cost ten times more than comparable non-match equivalents, owing both to the increased labor expended in creation and much more rigorous testing.
The XM1111 Mid-Range Munition (MRM) is a 120 mm precision guided munition developed for the Rheinmetall Rh-120 120mm gun (named the M256 in the US military) used by several Western tanks. It was also intended to fulfill a requirement for Future Combat Systems (canceled) for a long-range, beyond line of sight (BLOS) tank munition.
