I am, after many years, still very much interested in learning "Where did the misnomer 7.92" appear AND Why?!?!?! Only Excuse I have come across is some one with poor arithmetic stuffed this into some communication to then be endlessly re-quoted. PLEASE help an old mans confusion. Robert D.

I think 7.92 mm is the diameter across the lands in the barrel. That is how artillery barrels are measured. The bullet jacket is larger and forces itself into the grooves, in the same way the driving band of an artillery projectile does. Rod. Rcbutcher (talk) 03:49, 24 August 2012 (UTC)
