The .20 Tactical / 5.2x45mm is a wildcat centerfire rifle cartridge, based on the .223 Remington case, necked down to fire a 5.2 millimetres (0.204 in) caliber bullet. The .20 Tactical was designed by Todd Kindler and predates the .204 Ruger factory round. The case has approximately 0.2 grams (3 gr) less powder capacity than the popular .204 Ruger.
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).
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 is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
The exact technologies of this smart bullet have not been released. EXACTO was test fired in 2014 and 2015 and results showing the bullet alter course to correct its path to its target were released. [10] In 2012 Sandia National Laboratories announced a self-guided bullet prototype that could track a target illuminated with a laser designator. [11]

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.
