.32 Smith and Wesson Long by Kynoch

.32 Smith and Wesson Long inert round.

The .32 S&W Long was introduced in 1896 specifically for Smith and Wesson's first hand ejector revolver, also known as 7.65x23, Colt called it the .32 Colt New Police. Originally loaded with black powder but from 1903 was loaded with smokeless powder 

Brass Case with original lead FMJ Bullet replaced after inert process, photo shows typical example. 

Now a hard to get round since there is no legal pistol shooting in the UK, no licence required.
