Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

I wouldn't post them, due to the out of control litigation situation.

Here's some information on the cartridge itself:
https://en.wikipedia.org/wiki/7.7×58mm_Arisaka

Reloading data:

Probably a propellant such as IMR031, IMR4895, IMR4064 or IMR4320 would be good to work with.

I've had good luck using the PRVI 150 grain FMJs from Graf's, over 42.6 grains of H4895. The published Lee starting load is 41 grains of H4895 for the 150 grain jacketed bullets. I haven't had a chance to chronograph it yet, but the published data rates the 41 grain load at 2337 fps. A lighter load perhaps than the actual WWII issue, but close enough for my purposes. I see that Grafs is now also offering a 174 grain FMJ from PRVI. This could be used to develop a load that more-closely approximates the original Japanese loading, which used a heavier bullet weight. Shown are my loads using the 150 grain PRVI bullet. At the time I purchased them, they were the bullet whose profile most-closely resembled a military FMJ.
