A relic of pre-metric measurements
Interesting - so when did NATO/Western countries shift to those generally rounder numbers of calibre? Also slight typo, I think you put 7.62mm where you meant 76.2 (can you edit on Substack after publishing?)
NATO copied the US, which copied the French.
Thanks for catching the typo! I will repair that immediately. (Substack permits post-publication edits!)
