Wolf Steel availability for 6.5 Grendel and this 9x39 pretty much pushes my desire for a 300blk back behind the back burner.
I'm tempted by that 12.5" Wolf upper if it comes in 9x39 --- or do you think a non-piston would be better in case I eventually suppress it? |

Same price as the other uppers?

Is that the 9x39 or the first one in the video?

So who's gonna let something slip I know someone on here is on the list! https://www.youtube.com/watch?v=rLTwzsK1XB8 (Skip to 1:15 if you're not interested in their new T91 12.5" uppers) TL;DW: testing and evaluation uppers and ammo is set to be in the hands of the media types starting towards the end of next week. The hype is REAL View Quote |

my pics were taken at the assembly facility, but i failed to label them, so not sure of caliber
|

i did see the ammo they used for testing, all the writing is in Russian, very cool

I'm in for 9x39 for sure, also a yuuuge Vintorez fan and hoping this gets us one step closer to kits or rifles
Lately I've fallen down the suppressor rabbit hole and want to suppress all the things. 9x39 looks like it will be a lot of fun The T91 looks great too. A buddy has the 223 and it can shoot surprisingly well. I didn't check closely but it looked like he was getting close to 1 moa on our last range trip Z |

If this turns out to be awesome I'm 100% in for a short upper. Only question I have is will I need to get different guts for my 9mm suppressor to run this cartridge?

Quoted: That's a good question. In theory: yes....but theres a few drawbacks: the bullet is slightly larger in diameter than your standard 9x19mm so clearance and threads will be a factor. It also will be higher pressure but if its rated for .300BO subs then it should be fine. View Quote |

All kinds of things. The primary drawback is that you can't use 5.56 mags/bolts/cut down brass.

Just messing around with a caliper and, according to what I could find on google, the 9x39 measures a whole lot like the 7.62x39 in rim diameter, rim thickness, and overall length. It's a little fatter at the case mouth and shoulder but not by a lot. I wouldn't be surprised if a 7.62x39 bolt would work but no real way to check headspace on a mix/match bolt & barrel combination. Close enough to the 7.62x39 that it should fit in a regular AK mag or 7.62x39 AR mag.
A matched barrel/bolt set (add your own BCG) would be interesting to tinker with. |

Quoted: Good question. It's a military round designed to address the issues encountered on the battlefield with 200 grain 7.62x39mm subsonic ammunition. Basically it throws a larger diameter (.36 caliber) and heavier (278 grain) bullet. I spoke with the engineering team of one well known ammunition manufacturer well versed in the 300 BLK and they stated it would be much easier for them to produce effective subsonic expanding ammunition in 9x39 than 300 BLK as it was both larger in diameter and had more mass. They are also looking into doing supersonic ammunition for it as well. View Quote What's 300blk? |

I think the projectile for this is taken from the 9.3 x 64. Many years ago the soviets were working on a semi auto version of a dragunov in 9.3x64ish round. Dont know if it ever took off but it would make sense to use existing bullets for an existing case.
edit; Dragunov SVDK sniper Rifle (Russia) 9,3x64mm |

Quoted: Not at all. If anyone knows what is to be gained with the 9x39, it's the .300 crowd. View Quote to the table. They said it would be much easier making subsonic ammunition which expanded reliably and easy to make supersonic ammunition for it........ The larger diameter and additional weight gives it a number of advantages over the 300 BLK It makes a bullet designer's job much easier |
