Is there any definitive source on bore, groove, and bullet diameters, or rifling twist rate?

7.35mm suggests a nominal bore diameter of .289" and a nominal groove diameter of about .299" or .300", bullet diameter matching the groove diameter, probably with a relatively slow rifling twist, maybe 1:14" or thereabouts, for the bullet that was, even with its spitzer shape and aluminum nose filler, rather short and stubby for the caliber. All of this is, of course, guesswork. Does anyone actually know? — Preceding unsigned comment added by 2601:400:8000:A140:8099:9990:C5B1:3F22 (talk) 04:42, 24 October 2019 (UTC)[reply]
