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 .
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 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).
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 case contains the priming compound, usually in its own removable assembly called a primer. The case will also contain the charge of smokeless gunpowder, or sometimes black powder, and will be topped off by the projectile. Anti-glare: A grooved/textured surface detail found above the barrel to deflect light from affecting target aqquisition.
Bullets had the manufacturer code over the Quarter number and two-digit year of production engraved on the base (e.g. Pk/2-26 is Zaklady Amunicyjne, Pocisk, 2nd Quarter of 1926). 8mm Lebel "Balle D" bullets were differenced from 7.9mm Mauser bullets by a capital letter "D" inset between the contractor code and the date (e.g. Pk/D/2-26).
NRA Precision Pistol, formerly known as NRA Conventional Pistol, [1] is a national bullseye shooting discipline organized in the United States by the National Rifle Association of America. Emphasis is on accuracy and precision, and participants shoot handguns at paper targets at fixed distances and time limits.
A smart bullet is a bullet that is able to do something other than simply follow its given trajectory, such as turning, changing speed or sending data. Such a projectile may be fired from a precision-guided firearm capable of programming its behavior. It is a miniaturized type of precision-guided munition.
