Several years back,when Navy Arms was going by-by, I bought what was advertised as " Battle Field pick-up" .303 Britt ammo. I bought it by the barrel full and ended up with about 50,000 rounds. There were many unserviceable rounds as well as like new ammo in the mix.
I don’t have any head stamps older than 1909, most being early WWII. There are several hundred WWI as well.
I found one interesting round I can find no data on. It looks in all respects to be loaded in this manner for training or some other purpose rather than combat. The round is live,the crimp is in place and tight. The bullet looks to be swagged lead and is not cast. The casing is brass. The weight of the cartridge shows there is a powder charge of about 44 grains of something. ( empty case weight plus the estimated bullet weight of around 190 grains ) What looks like a firing pin strike is not, its a shallow gouge from another bullet point or has been dropped.
I only get baloney answers on other sights, I’m hoping you guys may have an idea.
