Americans use metric system for measuring bullets
- And drugs!
- And 2 liter bottles of soft drinks.
- Some bullets if they are nato standard or originated in europe. But other wise it can be based in inch or how many round balls you can make by dividing one pound of lead
  
  That last one doesnt even make sense. Do you have any info on that? Im curious now
  
  If the caliber is given in gauge or bore its the pound of lead i think. So a 12 gauge shotgun is the diameter of 1/12pound lead ball
  
  Muzzleloading rifles have their own hunting season, and reenactors go hard.
  
  Not just muzzleloaders shotguns are based on dividing a pound of lead
- Many videogames are in metric too. Battlefield and many other games use it.
- No? Caliber is based on the inch
  
  I'm far from a weapon expert, never held a real firearm in my life, but 9mm bullets are a thing, no?
  I'm fairly sure there will be a lot inch-based calibers as well; but one of the most known calibers has mm literally in the name.
  (and I know there are e.g. the .50 Magnum appearing in many movies/games; which is based on inch; but I would say less iconic than a 9mm; at least in the kind of movies and games I grew up with)
  
  Technically, the inch is defined by the meter, so it's all SI.
  
  Could be argued 44 magnum and 45 acp are more iconic than 9mm luger but the americans also uses the mm for 5.56 and 7.62 wich are nato standards. Funnily enough they dont extend this too the 50 bmg wich is called 12.7 where im from.
  
  Caliber can be based on a lot of things. Gauge and bore for exampel is based on the mass/volume (density?) of lead
