Speaking of accuracy, the Webley is on par with any full-size 1911 frame handgun, and I have reliably hit targets at 50 yards. An officer was expected to fire with his troops during volley fire during the 1880s, and the Webley was capable of hits out to 100 yards. At usual handgun engagement ranges of 25 yards or less, the Webley will print 3″ groups in single action with little effort. At 10 yards, double action will at least score you hits in the center mass area. Rapid fire, thumbing the hammer to single action, I have managed to do 6 round groups of 2″ at 10 yards on a regular basis.
Stopping power is one of the few places were ?experts? will question the .455 cartridge. It is a short-box cartridge that speeds a 265 grain soft conical bullet (this is the Fiocchi load ? pretty much all you?ll find commercially, although Hornady is doing a Webley round, now, as well) to 650-660fps. The muzzle energy is lower than a .45ACP by a bit and is on par with a 9mm round; recoil is mild, aiding in follow-up shots. Despite the lower energies, this is a big, heavy bullet and was plenty effective in combat. For a while, the British military was obsessed with ?knockdown?, and the .455 was considered highly reliable in stopping a target.
