I haven't seen anything like that on Midway now...

Hi,

Given my memory from 10 years ago or so, I doubt the Unique Powder load suggestions in your chart will even operate a T-14's action properly (hold open activated on last round).

If this is so, keep adding 1/10 of a grain, to the minimum load listed, until the action just holds open. You have then established your lower end base load, and can work up, very carefully, from there.

The gun rags have repeated, over and over and over again, that the 8mm Nambu is a sissy. Perhaps, it had to be loaded as a sissy, so that the inferior and weakly designed Type 94 Nambus wouldn't, simply, blowup.

Though it's certainly not a 9mm Parabellum, I'm not yet convinced that it needs to be a sissy when shot from a good, sound, Type 14 pistol, and would expect similar performance from it as from its European contemporaries (from which it was obviously, copied).
