9x39 build?

[mattri]

Anyone ever do anything with this cartridge? Looks like a fun round- is anyone making barrels?

Guess that answers that

What exactly is a 9x39? 22x39, 6x39, 7x39, but why 9X39?

Interesting...this s the first I've heard about the round and read about it.

The reason you haven’t heard much is because it was a com-block era FAILURE! Came out in the 80’s & Russia used it briefly...but just as quickly, DROPPED it! That should tell you something. Now, Wolf has resurrected it because they see a nich & are looking to make a buck. Issue here, is *some* ammunition manufacturers, in the last 7 years or so, keep telling us that somehow if you take a small case & use a REALLY heavy bullet over a tiny powder column...it makes the round “magical”! But only if it’s shot at us Subsonic speed. So because the bullets used are such high ballistic coefficient, it is stable to 500, 700.., ah hell.. a THOUSAND yards! Gimme a break. But people keep regurgitating this nonsense. Do yourself a favor a truly research ballistics. It opens one’s eyes to physical capabilities. Many years ago, researching ballistics made me stop following the SBR crowd in the AR community.
