The .20 Tactical is a wildcat centerfire rifle cartridge, based on the .223 Remington case, necked down to fire a .204" caliber bullet. The .20 Tactical was designed by Todd Kindler and predates the .204 Ruger factory round. The case has approximately 3 grains less powder capacity than the popular .204 Ruger. Handloaders can get velocities with 32 and 40 grain projectiles that almost match the .204 Ruger. Furthermore the .20 Tactical is also able to achieve these velocities with less powder than the .204 Ruger by more efficiently utilising high energy propellants such as Alliant Reloader 7 and Winchester 748. Based on the .223 Remington, a wide selection of brass is available. Lapua produces high quality cases in .20 Tactical sold under the Dakota Arms brand.
