ww2 bullets found while diving in Italy

[DigDuglas]

Went to Sicily last summer. Went cliff jumping/snorkeling/free diving off of east coast near some old WW2 turret. About 1/2 mile down was a spot a girl told me about. Said she found an old bullet. I found many after hours of snorkeling and searching. My favorite was the 45 acp head and the big one. Any help as to what they are would be cool

the big one in the pic with the .45 is a .50 cal. You would probably need to provide accurate measurements with a caliper to get accurate IDs on the others

OK thanks. I'll try to make some better photos with measurements. I couldn't quite get the lighting right.

The round nose bullets are probably Italian 6.5 Carcano, The second pic looks like it will be US 30-06 and German 8mm Mauser. But I'm just guessing based on the common bullets that are likely to turn up near Italian battlefields....

Measurements on length and diameter with a digital caliper will get a positive ID
