thanks so the glock was biggest caliber. so maybe the 40 killed gary?.40 caliber is 10.2 mm diameter
.22 caliber is 5.6 mm diameter
7.62 caliber is 7.62 mm diameter.
The 7.62 cartridge used was a 7.62x39 (think AK-47)
Not the 7.62x51 NATO cartridge (308 Winchester)
which is similar to the 30-06 Springfield.
