.308 is caliber in inches thus not metric.
BackOnMyBS@lemmy.world 6 months ago
why do they use decimal for imperial units?
Liz@midwest.social 6 months ago
Because even people who worked in imperial recognized that dealing with stupid fractions is stupid.

I have a 77/250 rifle at home because I’m a real American.
Karyoplasma@discuss.tchncs.de 6 months ago
Because they couldn’t rationalize using fractions.

It means the round fired by the gun is .308 inches in diameter, or 7.62mm. Gun caliber is measured in inches for Imperial.

Machining is often done in thousandths of an inch.
Mountaineer@aussie.zone 6 months ago
.308 is 7.62, civilian measurement vs military (there’s actually implications related to pressures, sidewall thicknesses, machining tolerances, but yeah same same)
Karyoplasma@discuss.tchncs.de 6 months ago
Yeah, it’s generally safe to shoot 7.62 from a 308-chambered gun, but not the other way around.
Enk1@lemmy.world 6 months ago
Same for 5.56 and .223.
