Third pic looks like 8mm Nambu made from 38ACP.


#3

Hmhm, these 10 cartridges in your first picture seem just some weird fantasy to me. But I have to admit: I do know nothing about wildcatting…Let’s wait to the comments of the specialists…


#4

Agree that was the closest match.


#5

Info on top item should say rim diameter .376


#6

hello
first picture: look like a try to make 7mm TCU ammo (7x44)

second picture:fantasy rounds made from 5.6x44 “flechette” cases

The 8 mm Nambu can be successfully made out of a myriad
of case types. This was done by individuals and commericlal
reloaders commonly prior to the availability of Huntington Die
Specialty and Midway cases in this caliber.

As an aside to my normal collection of 8 mm Nambu, I have samples
of loads made using reformed brass from 23 different case types.

Top collection of 10 appear to be the product of incorrectly-adjusted reloading dies. I have done that once or twice when adjusting dies, but not 10 times with the same caliber.


#9

Totally agree, the rounds in the first photo are reloading errors.

Thank you John. Let me know if you do not have the REM-UMC 38 ACP shown and I will be glad to ship you one on me.

Jim,

  thank you.  I have a sample of a round made on .38 ACP cases, as well as one made on a .38 Super case, which are the same in outer dimensions.  I don't save these by headstamp.  I do appreciate the offer though.  Until a friend educated me on these cartridges, I was not aware of how many different pistol, revolver, and even rifle cases, could be used to made the 8 mm Nambu, although I used to shoot a Type 14 (wish I still had one) with ammo made on .38 Special cases.  They split on the first firing, but created no damage to the gun, and functioned well with decent accuracy.  The were made by a chap named Spence. 

  The best case to use, actually, is probably the .41 Colt revolver case, but requires a lot of work on the case, and of course, is not exactly the most common brass to be found.

  Of course, the best case to use for making 7 mm Nambu is the 30 Carbine.  While I don't do so myself,  I own a nice Baby Nambu complete rig captured by a friend in WWII, with a great deal of provenance to go with it.

  Thanks again for your kind offer.  By the way, it is very difficult to legally ship ammo into California now.  A private party cannot receive even one single round at his home.  All must be shipped to a licensed dealer and picked up there.  Eventually, under the new law, that will require almost as much paper work as buying a gun.  Being a cartridge collector in California now is a lost cause.

Thank you for all info John.

Did not realize that California had tighten things up to that degree.

3 out of the 4 cartridges I was trying to clear from my desk were shipped to me last year in a mixed batch of ammo from a gentleman in Redwood California.

He and his family were chased from their home for a week by the wildfires.

Take care,

Jim Christian

The ones on the top are created by having the seating/crimping die down below where it would ever be correct. I found (having done it too) that once the crimp is as crimped as it can be, if the die continues down, something has to give. In this case, the weakest area is neck of the cartridge.


#14

Thank each of you for the info.

Still looking to id the 4th item – single cartridge


#15

This could be the MMJ 5.7mm AKA .22 Spitfire…Pete.


#16

MMJ 5.7mm or .22 Spitfire was formed upon the US .30 M1 Carbine cartridge.
