.300 AAC Blackout

Recommended Posts

300 Blackout or 7.62×35mm is a new caliber developed by the Advanced Armament Corporation. The bullet was designed to have similar ballistic properties to the soviet 7.62×39mm but designed to fire in regular AR magazines. Here's some ideas for it's characteristics:

  • Less velocity than 5.56 or 7.62 (subsonic optional)
  • Less range than 5.56 (around 150 meters)
  • Far more quiet than 5.56 when suppressed.
  • More effective in close range than 5.56.
  • More expensive than 5.56.
  • Barrels on the m4a1 could be modded to fire the bullet.

The team is aware of the 300 BLACKOUT (7.62 x 35 mm). The huge benefit with 300 BLK is the only modification to the m4 platform is the barrel. As you said, 300 BLK can be loaded for subsonic and supersonic velocities without any weapon modification. 

Expect barrels chambered in 300 BLK to be brought into Tarkov in time.

Is that an oficial screenshot from the devs themselfs, or is it just made up by someone?

I heard about .300 blackout, but didn't realize how easy it was to convert an AR system to use it. Pretty neat how it can use regular AR mags too. 

I wouldn't doubt we will see this implemented eventually.

AR fanboys will for sure never use another weapons platform again. :betoung:

One of the main selling points of 300BLK is that it is such a versatile cartridge.

You can have everything from 110 or 125 grain supersonic projectiles that can easily engage targets to 300 or 400 yards and are about the same ballistically as the 7.62x39 AK round, all the way up to 220 grain subsonic projectiles which are similar to the 250 grain subsonic 9x39 of the VSS.

All cycling reliably suppressed and unsuppressed in short barrels. AAC designed the cartridge to burn all it's powder in 9 inches of barrel meaning you can have a barrel in the 8 to 10 inch range and get most of the velocity possible with the cartridge. This makes it much better for short barreled applications than the 5.56.

This would be a great caliber that would give the ability to create an AK competitor, and with the implementation of a scope with something like the ACSS reticle it would be a close competitor to the VSS with it's ranging and drop compensating PSO-1 reticle. All in an M4 platform. This would give USEC the chance to have proficiency with weapons of a similar capability as the BEAR.

I would be mostly interested in a MK18/CQBR Block II configuration but chambered in 300BLK.tumblr_o23mxkEK8D1qc0pnjo1_1280.thumb.jpg.18c6fbfdbf3c22f3e66809274345ffc2.jpg

Although I prefer Geissele rails over the DD and KAC. The following is the Geissele MK4 but the MK8 is my favorite rail.

The 10.3" barrel and 9.5" rail of the CQBR Block II gives you as close of a fit as possible with a suppressor.

'More effective'. How are you qualifying 'effective'. 

Because 50 grain JHP's out of a 14.5" barrel are pretty effective when they hit soft targets. Do a lot of that fragmenting and exploding thing. 

If you were referring specifically to Full Metal Jacket, or M855, then I'd be likely to agree with you since the 5.56 tends to punch clean through at close ranges. But JHP's almost literally freaking explode when they hit a target because even out of a 14.5" barrel, muzzle velocity is greater than 3,000 FPS (The primary zone for the 5.56 round to properly tumble as it was designed)

 

Unpopular opinion of the thread- .300 Blackout is a fetish cartridge who's only decisive advantage is that it's a FAR better cartridge to use when running suppressors. Not just due to volume but do to reduced gas blowback, and it isn't as stressful on the internal of the weapon.

Implying I don't already

 

 

Since people brought Gun Porn into it a little earlier. This is Off Topic AF, but my Current AR build.

You are correct that light-weight hollow points fragment dramatically even out of 14.5 inch barrels. Generally, smaller calibers rely on fragmentation while larger calibers rely on expansion and penetration. However, as was stated previously, 300BLK is a more effective option when being fired out of short barrels. That is where the comments about 10 inch barrels came from and that is why the pictures of 10 inch barreled rifles followed. The pictures were intended to be related to the topic at hand; the fact that 300BLK is best suited to short barreled rifles. With a rifle like yours with a 16 inch barrel I would agree that 5.56 is a better option as you can take advantage of the velocity required for reliable fragmentation from that cartridge. That is why my 16 inch AR15 is chambered in 5.56 as well. Once you get down to 10 inch and similar barrels the velocity just isn't there.

The other thing to consider here is that 50 grain JHPs are really a varmint bullet that won't get much penetration even in a soft target. Once you add body armor they really aren't doing much. 300BLK consistently gets better penetration through intermediate barriers (e.g. car doors, windshield glass, drywall, etc.) within its effective range. That doesn't necessarily equate to better penetration through armor but it is important when considering you may need to shoot through light cover or concealment when engaging an enemy.

Even if you only consider the 300BLK as a replacement for the MP5 it is still a viable caliber as it gives you heavier bullets with greater sectional density and greater range.

Again, out of longer barrels, the 5.56 has obvious advantages that make it a better choice at longer ranges than the 300BLK. However, to say that the 300BLK isn't a more effective cartridge in short barreled applications within its effective range than the same configuration in 5.56 seems odd to me. Especially when we take into consideration that we are talking about a game where the 7.62x39 is already a heavier hitting cartridge than the 5.56, and the 300BLK and 7.62x39 have nearly identical bullet diameter (.308 compared to .311), the same bullet weight (depending on projectile selection), and the same velocity (assuming the same weight projectile is used between the two).

By no means am I saying the 300BLK is superior to 5.56 in every way and in every situation. I'm simply stating that it is ballistically comparable to the 7.62x39, is more effective than 5.56 when using short barreled rifles, and within its effective range will transfer more energy into its intended target than the 5.56. There is a reason many places have laws making it illegal to hunt deer with 5.56, yet legal to hunt deer, elk, and even bear with the 300BLK. The 300BLK is popular in the hog-hunting world because it is more effective against those tough-skinned animals than the 5.56 is.

I can get behind calling the 300BLK a niche cartridge, but calling it a fetish cartridge seems unfair to its capabilities.
