I understand the boom in 5.45x39 sales and AR uppers.
For what the cartridge offers, why hasn’t there been a push to bring 9x39 over and create AR uppers to use it? Surely with 7.62X 39 uppers and 9x19 uppers out there, building up a 9x39 couldn’t be that hard.
I saw(pictures) quite a few 9x39 rifles in the hands of Russian troops in the Georgian conflict. They mostly use it as a suppressed mid ranged sniper rifle. Although, their rifles are select fire…those Rooskies love their full auto. Appartently, because the bullet has so much momentum and sectional density, their penetrator load will defeat most body armor rated to stop a .30-06.
Since it’s still considered to be a modern military round, and a special one at that, I don’t see the Russians being too keen on exporting it.
Anything is possible to build, but it’s got to be economically viable to a manufacturer to get it into the pipeline, and right now, it’s not even a blip on the radar screen.
Im pretty certain that is not true. A 9mm subsonic bullet has zero chance of defeating Level 4 body armor. A heavy 250 grain 9mm rifle bullet has a lower sectional density than a 180 grain .308 bullet.
I suppose nobody has taken the dimensions from a photo, figuring out the unknown dimensions from the exterior based on the known ones in common with the 7.62?
Something to know about the 250 grain bullets: that’s 250 with steel. Lead would be heavier, giving it higher SD and energy for the same velocity.
