.32 Auto, also known as .32 ACP/.32ASP/ .32Colt Auto/ 7.65mm ACP/7.65mm Browning/7.65mm Browning M1897/7.65mm Browning M1900 and several others! Inert Ammunition. It became a very popular round and was used across a variety of pistols including the 1899/1900 Browning, WW1 Spansih Eibar and Savage 1907 to name but a few. I am puzzled wy such a small round was so popular as a military cartidge and it wasn't all down just to accepting what was avilable during WW1 as the Eibar pistols were made specifically in their thousands for the French forces.

Now a hard to get round since there is no legal pistol shooting in the UK, hence the price, free from explosive, no licence required
