.300 BLK

I just read about the .300 AAC Blackout on The Firearm Blog. He wrote about barrels and reloading dies, but I’ve never heard of this round before. So I went looking.

Here’s a writeup.

Here’s the official website.

Now, I’m all into 6.8 SPC because of the purpose-built nature of the round. Looking at .300 BLK? It too is being purpose built along the same philosophy as 6.8 SPC but attempting to address some issues with it. For instance, to use 6.8 in your existing AR you need to change the barrel, bolt, and magazines. With .300 BLK? only the barrel. That’s huge, especially if you’re aiming for adopting by the military.

Here’s a brief synopsis from the .300 AAC Blackout website:

 

Full power 123 grain ammunition matches the ballistics of the 7.62x39mm AK, has 37% more energy than 5.56mm M855, and 9% more than 6.8 SPC TAP 110. In fact, from a 9 inch barrel, the 300BLK has more muzzle energy than 5.56mm M855 from a 16 inch barrel. When 300 BLK is used in a 16 inch barrel, it has 23% more energy than 5.56mm M855 from a 16 inch barrel – with much higher-mass projectiles for a more dramatic effect on the target. Or choose subsonic cartridges for optimal use with a sound suppressor – 220 grain Sierra OTM (open-tip match) bullets vastly outperforms a 9mm MP5-SD in penetration and long range accuracy.

 

 

Look at that performance from a short barrel. Now stick a suppressor on the end of that, and you’ve got suppressed fire with adequate ballistics out of a rather compact package. Wow!

Of course, there are the obvious social implications. But I also think about hunting. For instance, using the same platform in the morning for deer hunting, then just attaching the suppressor and switching to a subsonic load for hunting hogs at night.

Go check out the official website. Lots of information, data, spec sheets, and even handloading information.

This is something I’m going to keep my eye on.

      I’d love to try being an early adopter of this, but just don’t have the cash for it right now. But if I had a few thou to burn, I’d probably have put in an order for stuff this morning. Looks wildly promising.
