8mm Nambu

[Madusa]

I?m considering casting bullets for this cartridge. Any idea?s? Do you think I can take a .355 95 grain bullet from 380 auto and size it down to .320? Maybe .355 115 grain would be better. Thanks for your advice 😃

No way in hell you could size any lead bullet down .035!! Three and a half thousandths, maybe. But thirty-five thousandths? Nope. Find the right mold, which might be tough.

If you need brass, you can still buy loaded ammo

Lee may still have dies for it

What about 8mm Mauser bullets? They are .324.
