the price of this ammo, it pays to reload. Both RCBS and C&H make dies,
though the RCBS ones are much more expensive. They cost US$125 or so, and the
C&H ones are usually about half that (I got my 8mm dies on sale from MidwayUSA for US$106; with shipping, GST and exchange they
came to around C$150). I tried to
order the dies locally here in
The RCBS shell holders for these cartridges are as follows:
7mm Nambu: RCBS shell holder #17 (same as .32 ACP and .30 M-1 Carbine)
8mm Nambu: RCBS shell holder #25 (only for 8mm Nambu). Dies are Series H
9mm Japanese revolver (called 9mm Nambu by RCBS): RCBS shell holder #6 (same as .38 Special, but it is recommended to slip a special washer over the brass when priming to keep from tearing off the very thin rim). Dies are Series H.
You can get these dies from Huntingtons or Buffalo Arms. There are links to both of these sources below.
Here is a photo of the little washers/spacers for reloading 9mm Japanese revolver cartridges. My husband made these for me from leaded (soft) steel.
This shot shows one part way on (left) and all the way down to the bottom (right).
Brass and Bullets:
The brass for the Old Western Scrounger ammo shown above comes from HDS, Huntington Die Specialties. They also make a special 107 grain TMJ bullet for the 8mm Nambu. They cost US$46.95 per 500, which seems very reasonable to me. Their website is:
Here is a close-up. The contour is not as rounded as the original Japanese bullets, but it is the same as the ones used in the OWS ammo, which has worked fine in the one Type 14 I have shot (my 15.11 date). I will have a report as soon as I get a chance to do some reloading. I am also going to try to cut one of the bullets open to see how they are made.
is another comparison shot, this one showing the 8mm Nambu
Midway has moulds for a 110 grain round nose gas check bullet for 8mm Nambu and brass from Bertrams of Australia. MidwayUSA is at:
http://www.midwayusa.com (type in 8mm Nambu in search box).
source of components is Buffalo Arms. Herefs a link to
their website: Buffalo Arms Co. - Search.
They sell brass in 7mm, 8mm,
and 9mm, as well as 85- and 100-grain 8mm bullets and 60-grain 7mm bullets.
Being in Canada I canft buy any of the ammo, but when I called them on December
15, 2003 they said they could ship dies and brass (but not bullets) across the
border, so I ordered dies in 7mm Nambu, 9mm Japanese
revolver, 200 rounds of 7mm brass, 300 rounds of 9mm brass, and a pack of five
snap caps. My order was held up because they were out of stock on the 9mm
Japanese revolver dies by C&H, so on
Here is a picture of the 7mm Nambu and 9mm Japanese revolver brass I got from Buffalo Arms. I have not loaded any ammo with it yet, but I compared the measurements to original rounds and to the specs in The Handloaderfs Manual of Cartridge Conversions (see below) and they seemed pretty close. The empty brass also chambered fine in my guns. It looks very well done.
The 7mm Nambu brass is reformed from new Remington-Peters M-1 Carbine brass, as you can see from this shot of the head stamp.
The 9mm revolver brass is reformed from new Remington-Peters .38 Special brass, as evidenced by this head stamp.
I eventually managed to get some of the Buffalo Arms bullets. They come in bags of 100 like this.
Here is one shown with the eraser on the head of a pencil for scale. They seem to be well cast but might need sizing, as they seem to be about .282h at the base rather than .280h. Still, I was happy to get them as 7mm/.280 is a very unusual size for a pistol bullet.
The Handloaderfs Manual of Cartridge Conversions by John J. Donnelly (Stoeger Publishing, South Hackensack, NJ, 1987) describes how to make 7mm Nambu cases from .30 M-1 carbine brass on page 801. It hardly seems worthwhile to make 8mm Nambu when you can buy loaded ammo or brass, but this book also shows how to make these cases on page 860 and how to make 9mm revolver on page 902. The 9mm revolver conversion looks reasonably simple but for the 7mm and 8mm I think one is better off to buy the brass freshly made or reformed unless you really enjoy that kind of thing.

I found some reloading data online at:
A more complete article on reloading 8mm Nambu can be found at:
There is also a very good article on reloading the 8mm Nambu and 9mm Japanese revolver cartridges in the February, 2004 edition of Banzai, pages 47-50.
I have not seen any reloading data for 7mm Nambu other than that on page 801 of the Handloaderfs Manual of Cartridge Conversion.
