I wonder what Barnes loads under their Vor-TX bullet? The factory Hornady 110 Vmax in my gun is a 5 inch wonder, the factory barnes 110 Vor-TX is a 1.5 inch deal. Also the Barnes shoots thru stuff quite nicely.

I still bet that with working on the gas port you can run subs with the quiet powders. Almost has to be. But I've been wrong 3 times in my life... LOL. No. You'd need an even shorter gas system, and a huge gas port, and probably a lightweight bolt too. Anything that would cycle with the fast pistol powders would have to be limited to those loads exclusively, and couldn't handle supersonics. You'd have to try those loads to feel the difference. The reason they are quieter is the pressure curve is very short, and the powder/gas volume is much smaller. For example, sub loads with Unique take a bit less than half the powder of comparable AA1680 loads. Bullseye loads use about 1/3 that much. That actually would work, but not for most.. I see no reason to run supersonic at all in the 300/221... if I"m going to run super... I"m going to run x39 instead... So if I can get my subs to cycle an AR, with the quietest powder that will be cool. A light carrier and so on, all makes sense, you should be able to make it all work with the right porting. I'm not at all up on gas system lengths but shorter does make sense. I"m hosed to a carbine length one thoug at the moment due to the rock barrel setup.

With powder availability (or lack thereof) being what it is, seems running an adjustable block wouldn't be a bad plan.

One could say exactly the opposite, why use a different gun in 7.62x39 when you could just switch mags and run supersonics in the 300 Blackout, and get pretty much the same ballistics, with better accuracy? Best of luck to you on that, you'll spend a lot of money chasing that pipe dream. You might want to actually try some of those fast powder loads before committing to it. You're right about being hosed with a carbine length gas system; even a 16" barrel is better with pistol length gas.

the 300 makes a lot of sense in 10.5 inch SBR's and pistols and I guess suppressed. It makes a lot more sense in a short barrel both super and subsonic than the 5.56. The 5.56 makes more sense in a 16.5 and above to me. A 10.5 inch pistol that produces 2100 FPS with a 110 grain bullet is an effective sub 200 pound game getter under 100 yards or so is my contention, similar to a 62 grain bullet at near 3000 to my findings. One thing about the 30 cal 110 Vor-TX, makes a bigger exit hole than a 223 TTSX.

I managed to acquire some 240gr Matchkings, and I'll probably experiment with them in sub loads. It will be interesting to see how they do out of a 1 in 8" barrel.

I don't see the 300 as a replacement for the 5.56, rather it offers something the 5.56 does't, a platform to launch 200+ gr bullets subsonic. While running an SBR with a can would make for a nice compact rifle, I don't see the 16" barrel with a can being a deal breaker for those that don't want the added tax stamp of an SBR.

I used to have a 16 inch noveske upper. With can attached it was out of balance. I then got the stamp for SBR for my lower. Bought a 10.5 inch noveske upper and sold the 16. Everything is good now.
