A wildcat cartridge, often shortened to wildcat, is a custom-made cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created as experimental variants to optimize a certain ballistic performance characteristic (such as the power, size, or efficiency) of an existing commercial cartridge, or may merely ...
The 7.62×40mm WT (Wilson Tactical) [2] is based on the 7.62×40mm wildcat cartridge, the shoulder of the WT was moved .003" forward and the throat was made .001" larger to accommodate mass-production tolerances while staying within the tolerance of the original reloading die tooling of the 7.62×40mm.

Source(s): Cartridges of the World, 10th Ed., Barnes The 7-30 Waters cartridge was originally a wildcat cartridge developed by author Ken Waters in 1976 to give better performance to lever-action rifle shooters than the parent .30-30 Winchester cartridge, by providing a higher velocity and flatter trajectory with a smaller, lighter bullet.
The .277 Wolverine (6.8x39mm) is a wildcat cartridge. It is a multi-purpose mid-power cartridge with increased ballistic performance over the AR-15's traditional .223 Remington (5.56×45mm NATO) cartridge. The use of a modified 5.56 case means that at minimum, only a new barrel is needed to convert any 5.56-based firearm to .277 Wolverine. [2]
ICL cartridges are wildcats based on conventional cases in use at the time. They feature a 45 degree shoulder [3] and the sides are straightened out compared to the parent cartridge. Most of the cartridges are considered improved cartridges since they simply create more powder space while maintaining the same caliber as the parent cartridge ...
.50 BMG cartridge (left) next to a .408 Cheytac cartridge. The .408 Cheyenne Tactical is based on the .400 Taylor Magnum, which itself is based on a modified .505 Gibbs, necked down to 0.408 inches (10.36 mm). The .505 Gibbs is an old English big-game cartridge that was designed to accommodate 39,160 psi (270 MPa) pressure.
