>pretty close in power to most lighter 10mm loads

 

Obviously not the intent. Easier to just use 10mm; There's a guy online that sells DI-operated 10mm uppers, if a person wanted an AR-platform "big pistol" build.

There's a good meme idea. Bullpup .224 valkyrie SMG. Of course, you're still going for a meme round; 9x25 dillon is probably fine for four out of five "needs a small machine gun" encounters.

 

It looks like the SCAR-H can be had in 300 blackout, which is a decent nod to slavic .30-cal offerings.

Not totally sure, but extraction is a part of the bolt face. So, center, hold tight into the chamber, and yank it back out with precisely linear force.

 

You can fudge bolt faces a little, but not a lot … but given the pressures involved I bet pistols (& PCCs) are less sensitive than rifles with 3-5x the internal pressures.

There are loads for 200gr rounds for both 300BLK, and 7.62x39 – or go 9x39, which was intended as a suppressed subsonic round from the get-go. Requires handloading, but who wants to get into guns but not handloading?

Showed this to a friend, who reminded me of work done on the .338 spectre. Same 10mm-mag base, bigger bullet with a different array of projectile choices.

 

My thought on it though, is I'm already going to have the SIG dies, I just have to set them up differently for the almost-rifle rounds, whereas I have no plans for anything .338 at all.

 

Still, thought I'd throw this out there for everyone's edification.

The steyr aug got big.

 

So, if I haven't asked yet, and maybe I'll repeat myself in the QTDDTOT, but

Since I'm now in love with this round, I'm wondering. Could I:

  • Buy a .357 reamer

  • buy a 9mm AR barrel

  • ream the barrel to .357 SIG but .3" "too deep"

  • drill (if a .750-straight, or .936-straight would be better) a gas hole about pistol-system down the carbine barrel a gas-system hole

  • put the barrel on a 6.8SPC-II ready BCG equipped upper

  • shoot a DI operated Sig Magnum AR?

 

2nd pic is, in fact, a custom built 10mm in sub-pistol DI (I wrote and asked him – he has a heck of a time, I guess, making them, but he has videos, they shoot fine)
