Windham Weaponry .450 Thumper

What we don’t have to guess about, however, were its outstanding downrange results. Because it’s a pistol, and we tested it with a non-magnifying Trijicon RMR red-dot sight (www.trijicon.com), we elected to reel the distance in to 50 yards, instead of the 100-yards the two magnifying-optic-wearing rifles also tested here were fired at. The Thumper’s precision was much greater than anticipated, printing a best 3-shot group of 0.50-inches with Hornady’s 250-gr. FTX Black load. Technically speaking, that makes this a 1-MOA-capable pistol at 100-yards…impressive! Group sizes from the other two loads tested—Federal’s 260-gr Fusion and Remington’s 260-gr. AccuTip—also turned in great, under-one-inch performance. Felt recoil was a smidge more than the other two guns, but suppressed with Silent Legion’s .450 Bushmaster can (www.silentlegion.com), muzzle blast was nonexistent. While the factory brake did its part to try and kill muzzle rise and felt recoil, it was loud…as one might expect a nine-inch-barreled .450 Bushmaster to be!

The Thumper’s short, 9-inch barrel proved to have no detrimental effect on downrange precision, with the gun turning in a best 50-yard group measuring 0.50-inches on the dot with Hornady’s 250-gr. FTX Black load.
