Caseless ammunition is an attempt to reduce the weight and cost of ammunition by dispensing with the case, which is typically precision made of brass or steel, as well as to simplify the operation of repeating guns by eliminating the need to extract and eject the empty case after firing. [2]
The 9×25mm Dillon is a pistol wildcat cartridge developed for use in USPSA/IPSC Open guns. The cartridge is made by necking down (reducing the diameter of the "neck" of the case to suit a new caliber) [ clarification needed ] a 10mm Auto case to 9 mm .
This muzzle device, described as a 'blast compensator', is a combination sound suppressor and muzzle brake, and is notable in its attempt at moderating the .50 BMG's muzzle blast and recoil, unlike contemporary large-caliber rifles, which are typically equipped with muzzle brakes only. Like the DSR-1, this rifle retains its bullpup ...
The cylinder is bored straight through with no step. Later versions used an inside the case lubricated bullet of .357" diameter instead of the original .38" with a reduction in bore diameter. The difference in .38 Special bullet diameter and case diameter reflects the thickness of the case mouth (approximately 11/1000-inch per side).
AV receiver: Also known as a home theater receiver, connects to a TV and decodes multiple audio channels to power a multi-speaker surround sound system. Preamplifier: It takes the weak audio signal from the source component and sends a stronger signal to the amplifier. Controls and selects audio sources, adjusts volume, and may offer tone ...
Precision-guided small arms prototypes have been developed which use a laser designator to guide an electronically actuated bullet to a target. [8] Another system in development uses a laser range finder to trigger an explosive small arms shell in proximity to a target. As of 2009, the U.S. Army has plans to use such devices in the future.

The bullet must also engage the rifling without damaging or excessively fouling the gun's bore and without distorting the bullet, which will also reduce accuracy. Bullets must have a surface that forms this seal without excessive friction. These interactions between bullet and bore are termed internal ballistics. Bullets must be produced to a ...
A more expensive home cinema set-up might include a Blu-ray disc player, home theater PC (HTPC) computer or digital media receiver streaming devices with a 10-foot user interface, a high-definition video projector and projection screen with over 100-inch (8.3 ft; 2.5 m) diagonal screen size (or a large flatscreen HDTV), and a several-hundred ...
