Mystery Drill rounds-alloy cases

[Flying10uk]

I have these 3 drill rounds which are perhaps a little unusual in that they are made of die cast alloy. They came to me via my father but I believe that he got them from a friend of the family who served in the British army throughout WW2 as infantry, thankfully without a scratch. He was with the BEF in France in 1939/40 and came out via Dunkirk with most of his personal kit, I believe. I also have his pre-war dated mess tins (personal eating/cooking utensils) which came with him out of Dunkirk. The same tins made the return trip 4 years later on D-Day.

I have never been able to identify the country of origin or weapon that these drill rounds relate to but they could come from any European power involved, at any point, during WW2. They are obviously not British because they are rimless and appear too long to be of German origin.

The micrometer dimensions are : 4th picture .303" dia, 5th picture .456" dia, 6th picture .427" dia. I have rounded up to the nearest whole thousandth of an inch.

Thanks for looking and any thoughts or suggestions are greatly appreciated, thanks.
