An now, for something completely different: Italian Breda 7.7 MG Fired Mk VII .303

During a recent episode of "The Lost Gold of WW2", while looking for hidden gold on an island off the Philippines they found a rimmed cartridge case, obviously fired, as it was only the case. They were really scratching their heads on whether it was WW2 American or Japanese. As soon as I saw it I knew that it wasn't WW2 American, because it was rimmed, and I assumed that it must be British .303 or Japanese. After some research they discovered that it was actually a pre WW2 US Krag case.

Looking online it appears that the Krag round is dimensionally very similar to .303 British but fractionally different.
