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.

Bullets weighing 2.6 g (40 grains) or less are recommended for optimal use in 5.7×28mm applications, [47] but the 228.6 mm (1:9 in) rifling twist rate (distance the bullet must travel to complete one full revolution) used in the firearms' barrels will stabilize bullets weighing up to 4.5 g (70 grains).
ME: Muzzle energy, in foot-pounds; P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains
