“The Type 38 spitzer-bullet round fired a 9.0-gram (139 gr) bullet with a powder charge of 33 grains (2.1 g) for a muzzle velocity of around 770 metres per second (2,500 ft/s).”, per Wikipedia (just under 2000ft-lbs at the muzzle).
That’s “underpowered” by WW2 MBR standards.
.30-06 with a WW2-era loading of 151gr M2 ball is heavier, faster (2,910fps) and has more energy (2,820ft-lbs).
8mm Mauser loads average around 3,000ft-lbs, with somewhat slower but heavier rounds.
So I can see why the Japanese might think the 6.5 round was a bit light, at the time.

Sadly, the “Old gun in a sea wall” looks like a spring powered toy. Kinda cool, though!

Why was a 6.5×50 caliber rifle round not powerful enough? I’m guessing full metal jackets.

I’m thinking the folks who think it’s a 1911 have never taken a 1911 apart.
