History
Adopted in 1891, the .455 Webley armed British service revolvers — most famously the Webley Mk VI — through both world wars. It threw a heavy bullet at modest velocity and earned a solid combat reputation in the trenches. Many surplus revolvers were shaved to accept .45 ACP in moon clips, a conversion collectors now regret.
