Twin Cities 67- reformed to 7.92 x 33mm


I wonder exactly what I have here.

Headstamped ‘TW (nato) 67’ it doesn’t look homemade but why would a US Ordnance plant be producing 7,92x33 towards the end of the 1960s? The thing that I find odd is that there is no neck crimp, strange in a cartridge for a self-loader. Is there a story to this cartridge?

Also, why no primer despite the ring crimp?

Happy collecting. Peter


Hand made from a 7.62mm NATO case, shortened. Very ordinary. I have numerous cases, both wildcats and factory wannabes, made this way.



I agree completely with Ray. I have seen many 7.92 x 33 rounds made from 7.62 NATO brass. This is not a Twin Cities cartridge, simply one of their fired cases turned into a dummy Kurzpatrone. It was common to make blanks for this caliber out of longer, existing cases, as well.

That solves that then, many thanks for the information.



I own a live and legal MP44.
I have made hundreds of 7.92x33 cases from 7.62x51 NATO cases.
RCBS makes a case forming dies set to do just that.


Here are a couple of other 7.9x33’s that were made from reformed cases.



What do the tip colours mean?



Peter - if you got that round in the UK there is a very good chance it is one of mine. Back when, I had a legal MP43 and reformed hundreds of rounds to feed it. There were not to many around in private hands even in those days.
