Bizarre cartridge case


#1

Recently found an old cartridge case that I have never come across before. It’s a .50 Browning case sized down to a .30 cal projectile. Produced in 1940, Berdan primer, with staining on the case from a disintegrating link belt. Any enlightenment anyone.


#2

Dingbat in my opinion. Lots modified as gimmicks, paperweights etc. Its ballistically impossible to ignite that amount of powder and get the products of combustion through a .30 cal barrel in the time allowed. Later dingbats now use 5.56mm
Anyone producing them contact me I can sell hundreds, thousands even!


#3

There are US military experimentals that fit that very vague & general description but as US, not Berdan primed.

(Vince see Hackley, Woodin & Scranton, HIstory of Modern US Military Ammunition Vol. 2)

Do you have a headstamp, how about a photo.

My friend has it, but I’ll get a photo and confirm the headstamp. I understand the ballistics involved and believe it to be genuine, not resized. I think one part of the headstamp was AUX. I just can’t understand why such a round. The projectiles would come apart in flight I would’ve thought. It’s like a 30-06 on steroids.

My opinion is, that your friends sample is German 7,92 x 94 Antitank round from WW2 period.

The German WW II AT small calibre cartridges all had the same Base Dimensions as the US .50 cal ( Both being derived from the T18 Cartridge design).
If there is a “aux” headstamp, it is Polte, Magdeburg, a Known maker of a lot of “special” AT German rounds. and all German cases are Berdan, as well…

And FN also made some AT rounds using the 13,2x99 Hotchkiss cases ( identical to .50 Browning except for Bullet diameter) in experimental “small calibre” AT cartridges. Again, Berdan cases.

Not a “Dingbat” at all…for shame… Jumping to conclusions like that…Must be the Insular attitude to all things “Berdan”…

That’d be it. Found a K98 bayonet in the same shed. In Far North Qld and there’s heaps of old munitions still around here from the war years. Just for interests sake, the headstamp reads: 17d aux W5A700 40.

Since these were used in North Africa, given the Find Location, I would say a souvenir (along with the Bayonet) from Aussie participation in the Desert War ( Tobruk etc and all that)

Years ago, there were rumours in collecting circles, of an original PzB39 AT rifle complete, brought back from N.Africa…in North Qld.
