Home Forums Hunting & Shooting AR and Tactical Rifles Building an AR 300 Blackout

Literally nothing you wrote is correct. Where are you getting this?


I'll make this easy- you have zero clue what you are talking about.



That'd not be a guess.

Yep.

the 30 carbine sucked against the Korean's or so I read on the internet. I shot a squirrel once with a carbine and ball ammo, it actually killed it.

The reason the 5.56 was adopted was because the 5.56 is light weight, compact, cheap, and has very little recoil.

This means that a soldier can carry a lot more ammunition for less weight (more than twice as much as with 7.62 nato), and less money; and they can fire their weapon a lot faster, and more controlably (especially in full auto). Also, the weapon itself can be shorter, lighter, and cheaper; because it doesnt have to resist the forces of a larger, more powerful round.

Yes, we adopted the 5.56 with a flawed wounding model, but in fact McNamara and the DOD didn't care... at all. What they were concerned about was that the 5.56 was light, and cheap. A soldier could carry 2.55 times as much 5.56 as 7.62 nato, but they cost the same.

Combined with the incorrect wounding model thought to apply to the round at the time, and the defense department (though not the military itself, especially the Army Ordnance Board), thought it was a win-win situation.

Well, it turns out they were wrong; and they knew they were wrong pretty quickly.

And now that our last 20+ years of conflict has been at , predominantly, street distance...the 5.56 is even more flawed.
A slower .30 isn't the absolutely answer but its an attempt.
My thought is a 7mm bullpup with fiber optic 2x and a 650-700 rpm ROF.

Regale is with all your high level military, shooting and killing experience with 5.56. Frost it with the same in 300BO. 7.62 as well. Don't forget 300WM. Oh and 4.6 to top it off.

How did you deal with the increased size and weight of 7.62 and the relatively poor terminal performance of 147gr ball? How did you get all your shooters to handle the recoil of a 7.62 battle rifle? Reliability and longevity? What was the average round count difference on targets between 5.56, 300BO, and 7.62 at close range? Did you notice mich difference between ball, Greentip, OTM, BTB, and A1? How did you deal with the increased wind drift past 200 with the BO? What platforms did you use? Barrel length? Subs or supers?

Yawn...
I spent many hours behind the A2. The BO beats it hands down in an urban setting.
I don't have to be standing on a pile of dead men to tell that.
The 5.56 works very well@ 3500.
Getting it there is less difficult than keeping it there.
So the great extended range superiority falls off when velocity drops, seeing that wound dynamics with such a small bullet depends on hydrostatics.
I suppose that there are some when faced with the train or the motorcycle would stay on the tracks because the cycly has more "energy"

The old "would you rather get hit by a train or a tiny car" cliche needs to die. Neither trains nor cars are penetrating projectiles that expand or tumble once inside you, so the comparison is absurd.

When bullets start running people over then it'll be valid. Until then, it's just a crutch, last ditch argument for people who don't know what they're talking about.

Ringworm in this case your simply full of beans or posting out of boredom trying to start a fight...

RW has always been an idiot, this is nothing new.

10-4.

deleted as offensive to a certain brand of rifle.

I thought it appropriate.

BTW I keep seeing uppers sans BCG for around 300 bucks IIRC, for the 300/221.....

I think it has more to do with the increased interest in suppressors. I have three 5.56 AR's, two 300 BO AR's and 0ne Rem 700 BO. Anything supersonic I use the 5.56/.223 but there's nothing more fun to me than shooting the blackout subsonic and suppressed. I actually harvested a Whitetail buck with my suppressed model 700 this past year. I don't recommend it but I did it at 30 yards with a 208 Amax.

Seeing as how the BO runs identical ballistics to the Kurtz and nearly identical to the Russian, your argument that its inferior to a 222 Remington is what's idiotic.
In the same platform, and fired from the same distance the little 22 loses.
I don't care that NATO hasn't adopted it...that's economics.
Physics doesn't lie.
And I am not to be influenced by people who think .223s are superior to shotguns inside dwellings.
Specificly a person who defers to what "organizations" do as his sole base of argument.
I am not overreached by a department head, council or CFO when making choices.
But, whatever guys. Enjoy your choice and have fun.

yes the M262 mod 1 will simply bounce off of 99.9999999% of everything, carry on...

Thats what I've been saying, its a pretty ideal round to run suppressed. Which is what I do. I've shot enough suppressed subsonic deer/turkeys now, that I can't recall the number. Over 10 for sure, I just don't keep track much anymore, and out to right at 175 yards.

Off topic, but yeah....I'd definitely take an AR over a shotgun inside a building.
