I have already posted that info to him. He is just trying to make a case that the cops could have used a .30 caliber sub-sonic M4 round to execute the bikers.
As a .32 bullet has a diameter of .3125.
And a 300 Blackout has a diameter of .308.
Only some 1.44% less
Do you not believe a 300 blackout bullet wound would be described as medium?
