Webley Mk III 45ACP

[Nom de Forum]

Quite true. Please note:

So it's a black powder design, which in later versions was modified to handle mild smokeless loads. In any case no Webley was designed for 45 ACP pressures, despite the coincidence that they can be modified so 45 ACP cartridges in moon clips physically fit in the chambers. Even if it doesn't blow up, it will shoot loose. Load them to the appropriate level and enjoy.

Yes, the first Marks of the Webley service revolvers were black powder designs just like the Colt Peacemaker and like the Peacemaker could be redesigned with stronger materials and design features to safely shoot smokeless powder. My point is that the Mk III and later Marks are redesigned for handling the pressure profile of smokeless powder (Cordite) loads.

I rechecked the load data in my post #10. Through oversight I did not give the 185gr bullet weight for the 5.7 WW231 load and listed 230gr and instead of the correct 225gr bullet weight for 5.0 WW231. After checking the 34 year old Lyman Cast Bullet Handbook that these loads were developed from I found the C.U.P pressures in the lower 13,000 C.U.P. range.

I would like to thank all who have posted to this thread. From your knowledge as put forth on this forum I have since gotten rid of the Webley and have pickup a S&W 1917/1937 (Brazilian) in 45ACP. Seeing that this revolver was originally manufactured to accept the cartridge, I wouldn't think that I should have any problems with the firearm. I hated to part with the Webley as it is a neat piece of history, but I don't need a hand grenade just waiting to go off in my hand.
