300 AAC Blackout fad over?

[Homer]

G'Day Fella's,

Rocker (sorry I haven't read any of the posts after your initial post on this thread.

FYI, I personally can't see the purpose of the .300 AAC BO, unless you are using it thru an AR or a rifle that utilises an AR type magazine!
Personally, I have been using the 7.62x39 cartridge with reduced loads (using Trail Boss) and bullet weights, from 130 to 180grns, with very good results!!!
Here is an image of my bolt gun and accessories.

FYI, I have a number of customers, that have .300 AAC BO's and many of them have had problems finding Safe working loads in these rifles!

Hope that helps

That was the idea.

The project's goals were:

Create a reliable compact .30-cal solution for AR platform
Use existing inventory magazines while retaining their full capacity
Create the optimal platform for sound and flash suppressed fire
Create compatible supersonic ammo that matches 7.62×39mm ballistics
Provide the ability to penetrate barriers with high-mass projectiles
Provide all capabilities in a shorter, lightweight, durable, and low recoiling package

It was designed for military purposes which don't translate all that well to most civie applications. It's easy enough to make arguments why it's not the best choice hunting/target shooting but I'll still get a lot of jobs done, and if people want to spend there money on one and enjoy it who's to say they're wrong really.

In a light rifle with a short barrel, it would make for a pretty decent pig gun.

Some people like wood, some people like synthetic, some people like more rail, some ppl like less. Some people like dressing up as women...but hey that's ok. Each to their own. If you love tacticool or 300b then by the mighty heavens you keep on lovin it because that's your thing and don't let anyone else tell you otherwise. Old fellars need to stop being so god damn old lol

"Old fellars need to stop being so god damn old lol"
The alternatives are:
Be young again......Id love that or
Fall off your perch.....not ready for that yet.

G'Day Fella's,

The Brass, there's not to many AR's in Civi's hands (Legally), in this country, hence statement!
Maybe I should have said;
I personally can't see the purpose of the .300 AAC BO "In Australia", unless you are using it thru an AR or a rifle that utilises an AR type magazine!

These days the whole industry is about hype and marketing this hype.I read all this stuff and have to wonder about things like personal defence etc.We don't even lock our doors here-I would be more concerned about the farm dogs and the farm wife-or the often out longhorn bull.All three have a streak of mean.Cheers

G'Day Fella's,

Yes BFB, one of my designs that I manufacture (and for both Super and Sub-sonic ammo).
This one is still in the raw, and hasn't been Cerakoted!

I dunno. Horses for courses. I can see it playing a similar role to 30-30. I'm a bolt guy, levers are fine but I prefer bolts. Now, the .300blk can be chambered in a lightweight carbine or very short barrel, and taken through the thick bush and scrub and still perform well. With a short barrel, it would also serve well as a gun for a farmer's Ute or ATV, etc. It's certainly not for everyone, and yes, it would definitely make more sense and have a larger market in America, but it would still have its uses over here. Add to that that it may weall soon be standardized by several militaries, and it should make for readily available ammo. Even if it soesn't , itM's a simple job to form your own brass.

As for me, I don't currently need one or have a use for one and don't intend on getting one (at least, not for the foreseeable future) but doesn't mean someone else doesn't want one or have a need for one. And I can also see the odd shot out .223 getting rebarrelled to .300blk.

[Homer]

G'Day Fella's,

I agree SG-Bill, Horses for Courses!
But I would rather be carrying a rifle, with a cartridge in the magazine that fits the size of the action.
By this I mean a .300 AAC BO in an AR or maybe a Sako L461 bolt gun!
If I'm carrying around a .308 length actioned rifle, I'd prefer to have it chambered in .308Win!
That way, I can down load it with Sub-Sonic ammo or use standard Factory ammo and have a far more flexible and useful rifle!!!

Doh!

A lot if not most sporting rounds come from mil or variants.

300BO is niche but strong. Once you own one you’ll not sell it.
I run the hornady 190 gr subsonic. Sound like a 22 drops fallow at 50 yards dead as a hammer.

300BO for me is wonderful. Ruger Ranch bolt with Holosun red dot and the accuracy is wonderful. I'm only using this for 100-150metres and it's simply much more fun than a 223. Will be making cast Hi Tek coated 140gr bullets for these for use at normal supersonic loads making costs per shot very reasonable and easier on the barrel.

Also have a Warwick with 300BO as well as a 223 barrel/receiver and only takes a few minutes to switch.

Don't knock the 300BO till you've owned one.

Those of you in Victoria there is an on line petition asking for suppressors to be legalised to reduce hearing loss for shooters. Suggest you fill in the petition. You never know one day they may allow us to shoot with suppressors. 300BO is especially useful for subsonic loads.

Old thread I know but there seemed to be a lot of people initially talking down the 300AAC. Be interested to see if anyone has changed their opinion. I own one and use it as a close range hog buster off a vehicle. In saying that I have shot pigs in the 80-90kg range at 200m with it. It is a great little rig. My .308 Rarely gets used nowadays.

[JimTom]

Just to clarify my last sentence in the preceding post, I am not suggesting that my 300AAC has the same capability as my .308. Of course that cannot be physically possible or true.

[SCJ429]

If I had a 308 and I wanted a subsonic 30 cal I think I would make do with what I had. It is not hard to find a bullet that will do the job and slow it down a bit. But if the Blackout is what you want, then go for it. You are going to be hard pressed to wear out a barrel in this lifetime.

[JimTom]

I agree with you regarding .308 and subsonic loads, I would just use my .308 however I actually haven’t experimented with subsonics yet. Have been shooting 125gn SST out of it at circa 1900FPS. I was actually going to buy a 7.62x39 however the blackout offers a greater range of projectile of course being .308 instead of .311
I use it as a close range pig rifle as opposed to subsonic suppressed mode for which I guess it is mostly used for in the USA.

[mickb]

Its not so much 308 vs 300 blackout for finding a subsonic load- either will, its how quiet you want to go. Not sure if you all have used suppressors but there is a considerable difference between light and heavy charges of powder in them. The Blackout has half the capacity and should also be small enough to make use of the faster pistol/shotgun burning powers with the right bullets, aka down into single digit loads of powder. You wont be doing that with a 308win.

You can indeed get down to single-digit charges of Trailboss in .308Win, which you have to to go subsonic.
I've been down to 8gn loads in 8x57mm with subsonic 180gn bullets.

[in2anity]

I built up my RARR to shoot 3p practical comps on the 100m and 200m lines, with the occasional crossover into hunting. They are an extremely light, handy little rifle still with an adequate lop. It definitely holds its own on the 100m and 200m line. I'm yet to test it properly on the 300m line, but on those blustery days, at 300m I think you'd be up against it (vs true long range cartridges).

I like it because it's economical. It only takes about 17grs of (fastest) rifle powder to fully fill the case which yields around 2100fps out of the 16" barrel (using a 125gr 30cal pill). With decent bullets, that load bucks the wind well enough at 100m and 200m.

Nevertheless, I reckon It's a finicky little cartridge. The brass around the mouth is thin compared to a 308w (after all it's stretched 223 brass). This means your up against it with regard to neck tension (compared to the 308w). And from my experience fast powders prefer tighter necks when compared to medium powder; you've always got to work harder to get fast powders consistently grouping.

I had to turn down my (collet) die's mandrel a fair bit to get it to group - even then, it's not really a sub-moa cartridge. I'd say It's probably more a 1 moa cartridge. I've got mine shooting about 1moa for 5 shots at 100m (when shooting from a chair). But I'm far from shooting 1moa from the elbows, so that suits me just fine

Are you using bullets that take advantage of the 7"-twist?

One word....Trailboss.
8gr under 190gr CBE plain lead (Alox lubed) turns up 980fps. (Like shooting standard velocity .22lr....hearing safe)
300 BO/Whisper is all about the AR platform....
Had one, a Remington. It is nothing like as versatile as it’s made out to be and lasted less than twelve months in my safe as there’s really nothing special or magical about it.
Was introduced after Mogadishu as a more effective ‘stopper’ for Africans pinging off their heads and spawned masses of 5.56 COAL small, medium and big bores.
Realistically if it runs a brass case, centrefire primer, propellant and a projectile....there’s nothing new or miraculous about it....it’s all been done before.

Blade racer did you read where I said faster pistol/shotgun powders early in the sentence?

The blackout will be able to use loads of 60% that trailboss load, aka just a few grains of stuff like Win231, unique, CFE pistol, bullseye etc. As I said you wont be doing that in 308win. Pretty basic physics, its twice the capacity, and most these powders will not be safe to play with.

Read my reply to Blade racer mate. Well aware of TB, comment related to the fast burning pistol/shotgun powders which in a small case like the Blackout you can also play with, as its same capacity as some pistol cases. Down to half that trailboss load, half the noise, more loading options( AS-30N, As350N, win WST, Win 231, CFE pistol, Unique, Red Dot, etc). Several of them also use lighter charges for more velocity than TB. You can't do that with 308win.

There is a difference between chasing "anything subsonic" and tuning in on low noise and accuracy in small cases. Its another entire sport. Look at the difference between match 22LR and 22LR quiets, or 357 at 1050 and 850fps after all. Supressors pick up this difference as well, they don't just "silence stuff"

Lastly 22LR standard is not hearing safe mate.Feel free not to use hearing protection, i hardly did in the day either lol, but maybe not the best idea claiming that on a public forum, its 130DB-140DB, and thats into hearing damage

Yep, I was referring to your incorrect statement that the BLK being smaller-capacity allows you to load down to single-digit charges, which you won't be doing with .308 - you can do that with .308. It's worth noting that ADI actually list a 10gn TB starting load for .308Win, which is under their own "60% capacity rule"...again.

I seem to spend a lot of time explaining this to supersonic hunters, there is a different between chasing "anything subsonic" and tuning in on low noise and accuracy in small cases. Its it's own sport. There is a big difference between match 22LR and 22LR quiets, or 357 at 1050 and 850fps after all. Supressors pick up this difference as well, they don't just "silence stuff"

I haven't tried pistol powders in the larger rifle cartridges so I can't comment on those, but TB does indeed "top out" on velocity, regardless of how much more powder you jam into the case. In 8x57mm I get virtually the same velocity for any charge from 14gn to 19gn of Trailboss behind a 180gn cast bullet - around 1400fps. Similar in the .243, but I did find a little better accuracy by continuing to increase the charge without gaining more velocity. In 7mm-08 8.5gn of TB gives me 920fps with a 145gn jacketed soft-point.

Standard velocity is quieter than that, 130-140dBa is for high-velocity .22LR. I wear hearing protection for supersonic .22LR, but not for anything subsonic. I would wear it if I was shooting a fair amount of hotter stuff but not for a few groups. I was shooting some 12ga. 28gm 1300fps loads the other day without hearing protection and it didn't make my ears ring at all. I think it's still a free country where we get to make those choices for ourselves. If I have people with me though, they get hearing protection. I was surprised when I attended a .22LR Benchrest shoot that they didn't require hearing protection.

[Tank]

Mickb....22lr standard from a rifle IS hearing safe all day everyday from a rifle in the open.
Suppression is a far greater factor in quietness than the charge used. The appropriate volume of the suppressor will render hi velocity centrefire ammo hearing safe....let alone subsonics.
But I’m not picking a brawl.
It’s a forum. We don’t have to all agree.

[mickb]

Yep, I was referring to your incorrect statement that the BLK being smaller-capacity allows you to load down to single-digit charges,

No you are attributing a context to make your argument applicable. My comment that you wont be loading down to single digits "with fast burning pistol/shotguns powders" like those used in 300AAC still holds. The fast burning/pistol shotgun powder I have now posted twice.

I can only apply a context and then clarify if there is a misunderstanding. Anything else is how badly someone wants to use a comment for a launch pad on semantics.
