Home Forums Hunting & Shooting Ask The Gunwriters 300 Black Out? Why?

What is the appeal or reason for the 300 Black Out...

seems putting the same twisted 30 Caliber barrel and using a 7.62 x 39 Case instead,
would give one a round a little faster and much easier to form and get load data for?

was someone just trying to reinvent the wheel?

You can convert a 5.56 rifle to .300 Blackout using the standard bolthead and magazines (and with the same number of rounds per mag). This would not be true of a round based on 7.62x39.

Something new for the civilian spec-ops warriors?

Subsonic hunting rounds with a suppressor.

the 300 blackout in supersonic version is not despite the claims to be so "as much" as a 30-30 but if you use good 110 grain bullets it will kill deer at close ranges just fine because I did it one year. At a dollar a shot for the factory barnes 110 tax-tx 300 bo ammo can put you in the ammo poor house only to get 2200 fps or so! I just let mine go, its not anything special for hunting and the 6.8spc is a much better hunting round which can be reloaded with up to 130 grain bullets. The M1 Carbine is the closest relative to the supersonic black out in my opinion.

I bought one....selling it...maybe in a AR it might make sense. I wanted it use it as a low recoil deer/caribou killer.

Then I realized I can just run H-4895 in my 308s and do the same thing and then step it up as the kiddos get older from there all in the same rifle. If I want subsonic trailboss in the .308 will get me there as well.

I have been shooting a 224Blackout for years. Great little round.

I sold mine. I figure a hit in the noggin with a 75 grain AMAX will drop all home intruders.

The 300 BO is a solution looking for a problem.

The 300 blk out, is a turd that you can't make shine no matter how hard you rub it. even the spec ops people don't use it. Rio7

Great for kids or recoil shy woman or anyone else....beats 30-30 everyday....

Correct.....that was my thought as wel until I realized I could run the same velocities with those bullets in a .308 win, but the 300 blackout can run full house 308 win loads or even come close. .308 just more versatile unless you are trying to fit it on the AR-15 platform I guess.

I like it, myself. It's a .30 carbine on steroids, which is hardly a bad thing. Runs well Super or subsonic. Same magazines and bolt heads as a 5.56.

Hodgdon has revised their data for Lil'Gun in the .300, and exceed 2400fps with 125's.

Because if there isn't a niche somebody will create one.

I have an acquaintance who will let me kill coyotes on his place if I use a suppressed .300 Blackout. He suggested this specifically. If I kill ten coyotes I can hunt big game there. So for me it is the only solution to this single problem.

Suppressed AR was the reason . but it does make a very low recoil short range deer killer . think youth rifle

I don't have a problem with it.

It's been around a long time, was originally invented as the .300 Whisper, the .221 Fireball necked up, in Contenders. Eventually was adopted & renamed as the .300 blackout by AAC.

The 7.62x39 has a larger case head, which theoretically makes the bolt less strong in the AR. The case has a pronounced taper and needs special magazines. The Russian round has a .310 Groove barrel, and bullet selections are not as good, though it may work with some .308 bullets.

The .300BO uses the same mags, bolt head, and can be easily made from 5.56 cases Load data is plentiful, and many folks are making special bullets for it. The .30 Caliber supersonic bullets are readily available.

have two.........Ruger ARR bolt gun.........Aero Precision AR........

why not ? cheap brass........Nozler 2nds boolits................fun & accurate !

In the AR platform, same bolt, same mags, more thump. A modern 30-30 is what it is.
