I was really enthusiastic about the potential for the 300 BLK on the AR platform after learning about it last year. The big news was that this caliber was going to be supported by major gun and ammo manufacturers so availability wouldn't be an issue. I soon started putting together my next AR build, which was to be for the 300 BLK. I'm glad to see that several companies like CMMG now have 16" barrels for the 300 BLK, but there's no use in getting the barrel if I can't get any ammo. What gives? I have a buddy who's in the same waiting game. He's at the point where he wants to give up waiting and just build another 5.56 or 6.8 with the parts he's assembled thus far.

It just seems to me like the whole thing is fizzling out now. The 300 BLK website hasn't been updated in ages and there's no news about ammo supply problems or the like.

Anyway, I'm not that far from giving up on the idea myself and just doing a long barrel 5.56 build instead.

Does anyone have the inside scoop?

Thanks!

Lots of people jumping on the bandwagon at the same time. I guess nobody knew the .300 whisper has been out for years. I dont really care for the blackout, but i will do a quick search for ammo.

CMMG will sell you 200 rounds of 147 grain supersonic for about $180. Hornady is also making supers and subs. Don't think its fizzling... more and more companies with 300 offerings including Lee dies recently. Big hold up is supers for under $13 from Remington. Don't think they would have any issue selling a ton if it was available. Think it was delayed by the decision to develop a longer bullet for it to make it feed more reliably. Many early adopters are reloaders. Cheaper to load for this than 6.8 with cheap brass and surplus projectiles.

Factory supersonic ammo is being made as fast as possible and withing the next 4 months there should be a lot more available in a couple different types. In about two weeks you should be able to find 125 grain Premiere Match 300 AAC BLACKOUT ammo for sale. After that there will be a hunters editions then sometime in October or November will be the cheap (hopefully around $12) supersonic. The gun has been out less than a year and has pushed the subsonic ammo availability which are now easy to find. It seems now they are playing catch up for the supers.

I don't think it is fizzling out as the release of the Lee dies took less than half a day to sell everyone of them on Midwayusa. When Midway also released the blemished 220 grain and other .308 pills that could be used in the blackout they were gone by late morning. I know some barrel manufactures are running over a month behind to get their 300 blackout barrels to the customers.

In the mean time here are a couple of places to pick up factory supersonic ammo:

CMMG 147 300 BLK Supersonic ammo

300 BLK 110 grain Hornady V-max Supersonic Ammo

Actually lots of people knew about the 300 whisper but it wasn't until 300 BLK solved the problems with the whipser that any large manufacture could invest the time and money involved in bringing the 300 blackout to the market.

Rsilvers is the man when it comes to AAC. Which is where the .300 blackout comes from

I'm interested in building a .300, and I emailed PSA to ask if they were planning on offering an upper in 16"/18"20". I was told that well luck, maybe we'll see a .300AAC upper from PSA next month.

Actually all you have to do is look on hornadys box of ammo or web site and it says:

Custom-grade ammunition from the factory. Built to the tightest tolerances for peak performance rivaling and sometimes surpassing handloads in many guns.

Based on the 221 Remington cartridge, the 300 Whisper cartridge loaded by Hornady is being offered in both a subsonic load (MidwayUSA #948-223 ) and this supersonic load, the 110 grain V-Max. Because of its low recoil, the supersonic load is great for recoil sensitive shooters. Also makes a great short range hunting catridge! Built for AR-15 type platform rifles, this cartridge is compatible for guns chambered in the 300 AAC Blackout as well.

Hornady's V-Max Bullets feature a polymer tip which enhances accuracy and promotes devastating expansion. The tip raises the ballistic coefficient for faster velocity and helps to stabilize the bullet in flight. It also acts as a wedge, initiating bullet expansion. The copper jacket provides the necessary bearing surface for maximum stability out of the barrel, and the jacket is built to withstand the fast twist rates of the most advanced varmint rifles. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Technical Information
Caliber: 300 Whisper
Bullet Weight: 110 Grains
Bullet Style: V-Max Flat Base
Case Type: Brass


Ballistics Information:
Muzzle Velocity: 2375 fps


Almost all whisper cartridges/ammo can be used in the blackout but blackout cartridges/ammo cannot be used in the Whisper.

I'm interested in building a 300 BLK as well. What is the optimal barrel length? I've been reading 16".
Anyone making a middy in 300?

If you are considering an SBR or subs, 300BLK is about as efficient as you are going to get and may as well go short 8"-10" pistol gas. If you will mainly plan to shoot supers and want to eek out some extra performance 16" is fine.

ETA: Middy makes no sense for this. Carbine is more than enough in this caliber given faster powders.

Remington stopped making the super. Not sure why, but you can get as much sub of theirs that you want.

They are going to rebrand the cheaper loads under the UMC brand, and have just started shipping the 125gr premium super sonic load.

Premium ammo vs plinking ammo.

The UMC stuff will be in the mid-high teens.
