9 mm ammo dude
Look at the clip above
I understand Boomer in English it is .356 caliber to be accurate
What is the caliber of a 9mm round? And why people call it millimeter instead of ".367" or whatever it is?
The caliber of a 9mm round is 9mm or .356 in.
I was only asking because I seen the rim fire in the clip, and don't really care just asked a question dude
