minus-squareMountaineer@aussie.zonelinkfedilinkEnglisharrow-up30·6 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)
minus-squareKaryoplasma@discuss.tchncs.delinkfedilinkarrow-up14·6 months agoYeah, it’s generally safe to shoot 7.62 from a 308-chambered gun, but not the other way around.
minus-squareKaryoplasma@discuss.tchncs.delinkfedilinkarrow-up10·6 months ago.308 is caliber in inches thus not metric.
minus-squareBOMBS@lemmy.worldlinkfedilinkEnglisharrow-up7·6 months agowhy do they use decimal for imperial units?
minus-squareLiz@midwest.sociallinkfedilinkEnglisharrow-up17·6 months agoBecause even people who worked in imperial recognized that dealing with stupid fractions is stupid.
minus-squareThunderclapSasquatch@startrek.websitelinkfedilinkarrow-up4·6 months agoIt means the round fired by the gun is .308 inches in diameter, or 7.62mm. Gun caliber is measured in inches for Imperial.
minus-squareKaryoplasma@discuss.tchncs.delinkfedilinkarrow-up4·6 months agoBecause they couldn’t rationalize using fractions.
minus-squareCaptain Aggravated@sh.itjust.workslinkfedilinkEnglisharrow-up2·6 months agoMachining is often done in thousandths of an inch.
minus-squareBOMBS@lemmy.worldlinkfedilinkEnglisharrow-up1arrow-down1·6 months agoso why don’t they write 1/1000 in then?
minus-squareCaptain Aggravated@sh.itjust.workslinkfedilinkEnglisharrow-up2·6 months agoBecause, unlike internet pendants, machinists have shit to do.

.308
Oh wait…
.308 is 7.62, civilian measurement vs military (there’s actually implications related to pressures, sidewall thicknesses, machining tolerances, but yeah same same)
Yeah, it’s generally safe to shoot 7.62 from a 308-chambered gun, but not the other way around.
Same for 5.56 and .223.
pls explain 🙂
.308 is caliber in inches thus not metric.
why do they use decimal for imperial units?
Because even people who worked in imperial recognized that dealing with stupid fractions is stupid.
