7.92x33 kurz!

[bobcat93]

How on earth am i just finding this cartridge.
It looks like it could be alot to fun out of a bolt action ..especially wildcating
Neck it down to .308 for simplicity, and selection of bullets.
Maybe even a .257cal.
Like i new 25-35 on steroids
Only one gun i believe was made to fire this cartridge the MP43.
A bolt gun could prove alot of fun. Brass is hard to find but the case can be formed from cut down 308 cases.
Is any one playing around with this obsolete cartridge. Or is it truly a thing of the past.
Its got some impressive case capacity @ 34.3gr.
And a 49k psi max pressure..
I dont see why you couldnt push this little cartridge to speeds that are acceptable around here.
Who has played around with this big little cartridge

I think you are all set for ammo, brass and dies. I don't know why anyone else hasn't tried it.

I seen my first one last week, stamped 8x33. I thought it was a 7.62x39mm at a glance. Pretty neat.

Does anyone have experience with cutting down cases?
Is the brass the same that far down a 308win case?
How far off the bottom of a case do you have to come up to stay out of that thick brass cup
Seems to me this is about the shortest one could cut a 308 case and still use it?
Is there a signal, or tail tell sign to cutting down brass.
What im asking is , if i cut down a case and can still anneal and form it (does that mean it is usable)
Or can that only be figured out by actual repeat firings to find out brass longevity of a wildcat.

Or does it start by picking a brass brand, cutting a case in 1/2 length ways and see what is going on with the parent case by taking measurements bown the side of a case for brass thickness.
Ive never been this far down the wildcat rabbit hole .
Of actually making a case. From another.
I hope that makes sense its kind of hard describing but i think you guys know what im saying..
No way to tell untill you sit down and start cutting anealing, forming and see what happens

Out of stock
Out of stock
Out of stock
That is why
Hahaha..
Maybe they only pump them out once a year.
But after some research
I watch some history of this cartridge and rifle videos
These rifles were every where in stock piles after the war. , they were gathered and sold to Pakistan or some one to farther their war efforts
So this cartridge is still in use just not in USA
Its alive still kick-n & still kill-n

What are you going to gain, satisfaction wise, buy going with a 7.92x33? I guess if you must, then go for it. Pesonally I would recommend a 30Br, or something based on the Lapua 6BR case. It's 38mm so you could prolly push the shoulder back and fireform it at 33mm if you went out and designed and sourced a reamer. Then you have dies to contend with. If 7.92x33 brass was readily available, that might be a different story. But, then you have the 7.62x39 Putin to think about also.

Just uniqueness man..style baby, STYLE!.
HAHA plus its fun to talk about
Once you neck it down to .308..its been done to death..lots of .30 cal cartridges readly available around a 34gr case capacity..
.25 cal could be even better

I did find something close that has been done already its a little larger
.308x1.50 Barnes

 

[bobcat93]

If some one wanted to make a standard 308x33 chamber
Could a 308 win barrel be set back and be done?
The same with a set of dies.
I could pick up any savage 308win rifle , and a set of lee dies and cut them with a band saw !
Have a custom wildcat hahaha
Im kidding..but is it really that simple? I think it would be.
How much would it cost to have a barrel set back and cut down a few dies
Any know..

Go with a 30 BR and get the advantage of all the work those guys spent developing it. The last guys that were all in on the 8x33 didn't fair too well.

I think I remember reading an article years ago saying that the 8mm Kurtz was the inspiration for the 7.62x39 Kalashnikov.
Here is a video talking about that very thing.
