Home Forums Hunting & Shooting Ask The Gunwriters 300 AAC BLACKOUT.....6.8SPC all over again?

rsilvers will the blackout chamber and fire in a 5.56 chamber?

when is Colt going to release a rifle in the Blackout?

Ask Colt - the Shot Show is a good time to ask them.

Already pointed out most of them in that thread. I don't have time to revisit them bi-annually.

Here's one from your post in this thread that is a perfect example:



Rather dishonest to compare USED once fired, modified brass for the .300 Blackout to brand new 6.8spc brass and then to claim the high side of 6.8spc prices.

A quick google search showed SSA 6.8spc brass selling for 46 cents a piece and Remington 6.8spc brass selling for 45 cents a piece. I generally pay 42 cents a piece direct from SSA as they usually have it on sale a few times a year.

I gave a range of prices. You are welcome to show the lowest price for 6.8 spec brass - even if it is reprocessed. I can't find any, but 300 BLK shooters have that as an option.

I see SSA for 52 cents each and it does appear like it is sometimes 46 cents each.

In 300 BLK, new Remington primed brass - 27 cents each even in small quantities of 100 pieces:

Once-fired but reprocessed brass - 10 cents each:

Looks like the Blackout might be cheaper to reload, brass is cheaper. I don't think it will be quite as flat shooting as the 6.8 but for close range its probably OK. Again will a blackout round fire in a 5.56 chamber or is this something you have not tried.

I like sighting in my rifles for "max point blank range" with a tolerance of +- 3.5 inches.

300 AAC Blackout UMC would be about 236 yards - where you could shoot with no sight adjustment.

6.8 has a longer range - let's pick an example - say SSA with Nosler 100 grain AccuBond:

http://www.ssarmory.com/6.8_spc_ammo-Nosler_accubond.aspx

That has a max point blank range of 286 yards.

So that is the reality - 50 yards more range of not having to adjust your sights.

On your other question - you should only shoot 300 AAC Blackout ammo in barrels that are marked as 300 AAC Blackout or 300 BLK. Doing otherwise is potentially dangerous, and can lead to injury or death to you, bystanders, and damage or destroy firearms.

you answered both questions. I would zero the 123 at 200 yards (3 inch sight height from bore) and call it good at 2200 FPS starting velocity and a .325 or so BC.

By the way, you can also zero elevation at 32 yards as that is the near-zero for 200 yards. And maybe fine-tune windage at 100 yards.

thank you I looked at an AAC upper at Bullseye, I liked it because it was so light. I like that Knights flip up sight.

Sorted by energy at 300 yards:

The traveling salesman for AAC makes his bi-annual drive by BS.

Time and time again you make outrageous claims that never pan out then disappear for a few months, only to appear again when a .300 AAC thread appears and you throw out more outrageous claims and claim the check's in the mail... rinse, repeat.


Actually I PM'd Robert about this thread because I am an AAC customer and care quite a bit about them and their continued success.

I don't see the problem if any any with the thread? Its a typical my cartridge is great, yours sucks thread exacerbated because there is some hostility surrounding the way Remington kind of dumped the 6.8SPC. In the end both the 300 blackout, and 6.8SPC will survive our dissection. The 6.8 with the 85 grain bullet is nothing more than the old 250 savage and this cartridge killed a lot of deer. The 300BO is so close to the 7.62 x39 that with a blindfold on you could not tell the difference, of course the 7.62 x 39 has killed a lot of things including people for a long time. So if you want a 10 pound semi auto buy a 308, or a LW Bolt gun in what ever cartridge you choose etc etc. In a reasonably sized semi auto AR type the choices are limited and the choices are more similar than different.

I have a handful of C product magazines that work great. Now that they are defunct, I'd try the ASC mags.

Now the breaking bolt issue may be another story. I have an AR Precision bolt that has not yet had a problem, but time will tell.

300 AAC Blackout UMC is the #1 most popular rifle cartridge at MidwayUSA - there is no 223/5.56mm load - or any cartridge for that matter, that is higher ranked.

300lbs, 100 yards, Barnes T-TSX 300 AAC Blackout Black Tip ammo, AAC 16" upper - dropped right there.

And to think I had thought the .30-06 was the most popular.

All 30-06 load combined - yes. Just not any individual load.

This Blackout stuff is great! It's almost like you've convinced yourself you've come up with something ground-breaking.

I played with the 300 Whisper about 8 years ago in a 16" AR. It was very accurate and hell on deer with 150 grain Ballistic Tips. Mine was not 100% reliable on cycling the bolt with subsonic loads though. I used the factory 220 grain Cor Bon loads and handloads both would not cycle reliably. That may have just been my rifle though.Ejection with with the 150's powered by H-110 was brisk however LOL.
