Allegany Ballistics Laboratory (ABL) located in Rocket Center, West Virginia, is a diverse industrial complex employing some 1,000 people across 1,628 acres (6.59 km 2).The facility is a member of the Federal Laboratory Consortium and is operated by Northrop Grumman (former Alliant Techsystems) under contract with the Naval Sea Systems Command (NAVSEA).
Handloaders can get velocities with 2.1 and 2.6 grams (32 and 40 gr) 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 using high energy propellants such as Alliant Reloader 7 and Winchester 748.
Alliant Techsystems Inc. (ATK) was an American aerospace and arms manufacturer headquartered in Arlington County, Virginia. The company operated across 22 states, Puerto Rico , and internationally. ATK revenue in fiscal year 2014 was about US$4.8 billion.
Renowned firearms author John Taffin has published handloading data for the .22 TCM in GUNS Magazine on two occasions: in 2017, focusing on powder loads, and in 2023, addressing the use of various projectiles. Using Rock Island Armory M1911 pistols with 5-inch barrels, Taffin conducted tests at 20 yards with four-shot groups.
A QuickLOAD user most certainly should not just "plug in" a cartridge, bullet and powder and use that load, assuming it is safe. It is good practice to double- or triple-check QuickLOAD's output against reliable load data supplied by the powder producing companies.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
The data are all for barrels with a twist rate of 1 turn in 10 inches (250 mm) which is needed to stabilize the heaviest bullets. The higher muzzle velocities reported by Nosler for 165 grains (10.7 g) and heavier bullets use loads employing a slow-burning, double-base powder (Alliant Reloder 22). [citation needed]
