300 Black Out - what is this?

Here let me help

@ Artful:

They did not talk about the ballistic effect of wind on a heavier round in the video, but I can hunt with this beast! Talk about one rifle platform doing it all! Any information on using this platform for high power rifle competition?

Nice video

Cane_man - as the 300 Blackout can be run as Supersonic, Subsonic or both the gas port position can be important.
for Subsonic you see a lot of pistol or carbine position for Supersonic you see Carbine and a few rifle length gas tubes
but for the ultimate in versatility this one is probably it - dual port drilled barrel with variable gas feed.

Now THAT makes a ton of sense. I have to work that into my 300BLK plan.

Terminal ballistics over 300m can't keep up with an AR-10 in 7.62. Too short an impulse with the powder.

Of course not, it isn't what it was designed for. The M40 can't keep up with the M82 either...

Interesting round. There is a subsonic round for the 7.62x39 rifles. It is a 230 grain boolit in the 7.62x39 russian round. . I'd like to try a subsonic round to see what it's like.

With the Blackout its cheaper to load than the .223 or 5.56.
I can load a 155gr cast lead bullet that makes 1800fps and only costs are 3 cents for primer, 3 cents for gas check and 5 cents for powder. My lead and time is free.
For the .223 I need the 3 cents for the primer, 8 cents for powder and 10 cents for a bullet if i can find one.
So basicily its 21 cents for the .223 verse 11 cents a round for the blackout.
P.S. I could get a gas check maker or find gas checks right now. But bullets for the .223 are impossible to find.

I heard about swaging 22LR cases into 5.56 / .223 tips using pure lead cores. Does this eliminate the need to gas check? Sorry to you BP folks if this cuts in to your Pb supply. Any idea what the tools would cost to do this?

To swage .22 into .223 Jacket bullets cost about $800 to $1000, see swaging section for details. Plus its a lot of work.

It is a cure for a problem that didn't exisit.

+ 1 on this. No real need for it, kind of like a 32mag.

Oh, bunch of .32 fans heading your way now.

There is also another .30 cal. ctg. variant using a cut down 5.56 case, the 7.62x40WT. It uses a 1-12 twist barrel, holds a bit more powder, but the down side of being a semi-wildcat. If one is reloading, it isn't an issue.
