My Eureka Moment !!!

My Schofield's BB cartridges fit and work perfectly in my BB Webley Mk.VI pistol, and transversely, my BB Webley Mk.VI cartridges fit and work perfectly in my BB firing Schofield pistol, too!

For notwithstanding the fact that the Webley cartridges are stamped 'Webley' around the brass lip, and the Schofield cartridges are stamped 'Schofield' around the brass lip, both cartridge types are identical and fully interchangeable.

Guess they must be made in the same factory -- or at least to the same specifications -- which given the known marriage between AGS and Webley, if you think about it, is not too surprising? I really find this discovery very refreshing, and wanted to waste no time in letting you know. Viva La Standardisation.
