Need advise on 8mm Nambu

I would like to begin reloading the 8mm nambu so I can shoot my Nambu more affordably. Can anyone give me the recipe for a duplicate load of the original or close enough to be safe? What products do I need to buy besides the dies? Thanks,
Rhett

I have the same question, as I want to get set up to do this. I need the dies for 8mm and 6.5mm rifle.

I've used with success rcbs dies,huntingtons plated bullets and cases sold by graff. My load is 4.2-4.4 grains Win 231 powder.FIRST make sure your t14 is in good condition. I can't stress this enough. Make sure your recoil springs are not broken. Wolfe springs make very nice original power rated springs. The nambu is very cool to shoot.I have a junker that I shoot and the bolt likes to oiled down first.I also have a bullet canneluring tool I roll my own groove and seat the bullet with a very positive roll crimp.cartridge oal is 1.250" Thats 1 1/4" for you non-decimal guys. Good luck.

Big Ed,
What weight grain are your bullets?

I use a 103 gr. cast lead bullet and 4.8 gr. of Unique. This is just enough power to operate my gun as a semi-auto. Your gun may react different so start at a lower powder weight and work up. Good Luck

I believe the huntington bullets are 107 grain.Go to thier web site and check them out. I can't get to them easily. There at the bottom of my vast pile of reloading brass/bullets etc.

I have some off-the-wall input on this.After a box($50!) of Dangerous Dave's Old West Scrounger nambu ammo,I noticed if you chambered a round,then ejected it,it came apart! This happened in a minty 14.5 t14 and a t94.I noticed the 3 ***** punches were absent in the neck area of the rounds.Do you use bullets that can be chamferd(sp)? Sometimes they come apart just jostleing the box.Not good at a buck a round....Scott

Scott,
My canneleur tool came from C&H it does a very nice job on putting the groove in the bullet. Since they are copper plated lead bullets they groove easily.When I seat my bullets I make sure I get a very strong roll crimp. I feel its necessary because of the steep angle of the magazine ramp and speed at which the nambu action works.If your pulling bullets out perhaps the ammo you bought has little or no crimp.I also use original (new made) cases as I feel these give maximum reliability and reload potential.

Yea,that's my point on the Dangerous Dave(good name) ammo,the bullets held in by The Force!There's no canneleur or anything. It "should" at least be pin pricked around the case mouth like the original rounds,since the bullet isn't seated very far in.I would just stay away from buying that brand of pre-loaded rounds again.

I'll scan the old Midway data and post it sometime this week. Never had problems with my loads and I don't crimp squat. Ran about 150 through a T100 SMG on Blevins' mountain two weeks ago. I load 4 to 4.4 grs of Unique with 102-107 FMJ bullets. Finding affordable brass is the real bear to tackle.
