A few 1:1 scale replicas of the Webley .455 cartridge used in their famous revolvers.

The Mk III is the “Manstopper” round, developed in 1898 and banned the following year.

The MkVI is the standard round used in both world wars and is identical in shape to the older MkII.

I use these to demonstrate the size difference between the .177 pellets my replica Webley fires and the things that the original used.
