Round that has killed more people than any other ? 9mm ? NO ,7.62x39.
9mm is number 2 ,followed by 7.62 x 51 /3 ,then 30-06/8mm hard to say/4
then 45 , they lumped this together with ACP&45lc/5 then believe it or not 22LR /6 then 38/357 /7 then 30/30 win./7 then 69cal BP/8 then after that it was hard to tell ,the British 405 was a contender but with the records we have its an if.
Calibers above 45 ,Number one 50BMG , two 20mm after that it was hard to tell.
This was only an estimate ,on JANES ,when a writer there was asked.
Only the first two are most likely reliable ,But bullet is defiantly 7.62 ,all round killer of all time.
This was only this guys opinion ,from looking at war and crime stats. what do you guys think ?
But it looks like the American 30cal ,is number one ,even this day on June 6 1944 ,up untill now.
