Some Webley Mk VI's have blown with standard .45 ACP loads, which run 21k psi, half again more than the standard 12-14k psi of the original .455 load.

I am well aware that some of those old guns have been fired many times with .45 ACP with no problem, I don't recommend it since every round is heavier than the .455 proof load.

Just in case folks think this is some kind of recent scare story, in 1916 the War Office warned against firing the .455 Webley Auto cartridge (which has about the same pressure as the .45 ACP) in any service revolver, including the Mk VI.
