That’s not fair. We also use it to weigh drugs
It’s also used in measuring soft drinks like the 2 liter bottle
And only some of the bullets.
I think it started for the same reason we have metric tools; foreign imports.
Some of them we disguise the metric cause it’s anathema to us, 30 aught 6 for instance.
Look at what we’ve done just to not have to refer to millimeters!
30-06 is a 30 cal bullet which should be 300 thou but is really 308 thousandths of an inch and is commonly designated a 7.62 mm NATO which it isn’t because that’s measured at the inside of the lands, so its actually 7.82mm.
Simple.
7.62 NATO isn’t the same thing as 30-06. 7.62 NATO refers to a specific cartridge, not the bullet projectile itself. It’s the same as .308 Winchester. 7.62x51mm.
30-06 is 7.62x63mm
Damn, you’re right.
