I think it’s strange Sierras dim on the bullet is .308”.The unimproved
I've yet run across a source that says the 7.7 Arisaka was a rimless .303 Brit. The Japanese at the time tended to copy whoever was best. For example, their Navy was drawn from the British. Their military was initially French until they loss against the Germans. China acquired a lot of German WWI surplus. When the Japanese invaded China with their 6.5 Arisaka, they encountered the 8mm Mauser used by the Chinese. The Japanese already had the Lewis gun with .303. And the change of the Japanese fighting the British was higher. The Russians used a .303 bullet of their own. So, a necked down 8mm Mauser was adopted. My experience, my Arisaka shoots best with hot loads. That's beyond the .303. But why is the 7.7 Arisaka loaded so low? I don't have an answer. Maybe because the Japanese soldier was small and these soldiers couldn't handle a full load?7.7Jap is based on the British .303 Mk.7 cartridge but cut into a rimless shell to help it feed better in a Mauser action. In theory I’m guessing this means any powder and projectile that works well in the rifle No.3 Mk1/1*. (?). My goto powder for the No.3 is IMR 4064 with IMR 4895 as a standby substitute. The Sierra 180gr RNSP is a great hunting bullet for the .303 so it should play well in the 7.7 also. The Remington 174gr FMJ component bullets are excellent for target shooting but I haven’t seen any in years. Maybe check out the auction sites.
Maybe you mean .312" bullets are not easy to find? Speer and Sierra are .311"I was looking for Jacketed bullets locally, .311 is not easy to find
So you saying…. I can’t stop laughing at the 7.7 vs. 303. BTW.. british men were also historically very short & small because of their diet. Big Men is a very much Modern inventionI've yet run across a source that says the 7.7 Arisaka was a rimless .303 Brit. The Japanese at the time tended to copy whoever was best.

I think because they operated in the tropics. High Temps affect pressure quite a bit.I've yet run across a source that says the 7.7 Arisaka was a rimless .303 Brit.

Those are the sets extreme spread and standard deviation.Nice . What do the numbers at the bottom mean?
Ah, ok. Haven't worked with standard deviations in 30 years, ugh. What kind of groups were you getting?Those are the sets extreme spread and standard deviation.
I couldn’t load last night… Long story involving whiskey, but Those LOOK good!
