6 Reasons to Reload the .300 Blackout

by Joseph von Benedikt   |  October 11th, 2013 18

The .300 Blackout is definitely a Kool-Aid kind of cartridge—you either love it or you don’t. Nobody I know has a Homer Simpson-like “meh” attitude about it.

Me, I’m on the dark side. I have yet to wholeheartedly buy into Blackout Fever. Why? Because it’s not particularly good as distances stretch past a couple hundred yards, and when I stuff a cartridge into a rifle, I want it to act, well, rifle-like. Until recently, I considered the .300 Blackout a very non-versatile cartridge.

A friend of mine, a ballistician at Barnes Bullets, made a comment that recently caused me to grudgingly crack the door and consider the Blackout more objectively: “It’s the best carbine cartridge out there for combat.”

A lifetime of gun technicana and a recent tour to Afghanistan backed his comment up. “What about long range,” I prodded.

He looked at me as if I was an idiot. (Could be he’s right.) “That’s what designated marksman and snipers are for.”

OK, in a team scenario, that made a lot of sense. The discussion continued. “What about for individual use? It’s not very capable as distances stretch.”

My buddy politely made the point that neither are most shooters, and closed his argument with the undeniable statement that within the ranges at which most conflict occurs, the .300 Blackout has considerably more impact authority than the 5.56mm.

My bias wasn’t exactly squelched, but it was cracked, and other considerations came flooding in. Finally, I had to admit perhaps, after all, the .300 Blackout is a very versatile cartridge, especially if you handload for it. Here are a few prime reasons why.

    The SKS and the AK-47 use the 7.62 X 39. A popular round today available most anywhere.

    • Swatdog273

      But you cant use that round in a normal AR platform using the mags, BCG, and everything else that is AR. The AR 300 blackout is tremendously more accurate than an SKS or AK. I have shot them both a considerable amount

        If you want .30 cal performance out of an AR platform.
        300BLK is an outstanding choice. If you want a gun that will go BANG
        every single time, no matter what the weather or terrain or cleaning
        kit. Pick up a Kalashnikov. (minute of angle accuracy is over-rated
        when someone is shooting at you, but a malfunction in that same
        situation will cause one to soil their britches quickly.

          Steven C, I understand what your trying to convey, unfortunately, accuracy means everything. If you want to go “gang-bangin’ ” in the hood, and don’t give a crap about who gets killed, go get an AK (any variation). If your an operator, or shooter of any caliber, you want the acccuracy of an AR-platform. And after 22 years in uniform running and gunning, and the last 8 years as a DoD employee, the 300 BLK definately fits the niche it was intended for. Minimal cost in conversion, excellent terminal performance at realistic engagement distances.
          But everyone will have thier preference either way, regardless of facts.

    I have both the 7.62×39 and the 300BLK in AR and I reload both with the same bullets and powder. For me their performance has been identical. The deciding factor for me is ability to repair and availability of parts. I can get on any firearms website and find parts to fix or upgrade my weapon. There are no rivets, welds, or pressed on parts. With American barrels they are both identically accurate. Not hating on the AKs or SKSs but I dont own a machine shop so I stick with AR.

    • Steven C

      I may be wrong here, but I am under the impression that 300blk barrels are rifled to support heavy for caliber, subsonic bullets as well as the normal weight bullets at super-sonic velocities. The SKS and Kalashnikov’s are rifled only for super-sonic velocities (i.e. a slower twist than is required for sub-sonic).

    • Charlie Bales

      Be careful do not reload AK bullets into your AR they are not the same caliber, the barrel for your AK uses .311 cal like that for the .303 British Enfield not .308. The AR uses plain ol’ .30 cal. (.308’s) You can get away with .308’s in a .311 but not the other way around (dangerous pressure levels)

  • dltaylor51

    The 300 bo is every bit as good as the Russian and considering it has the same head as the 5.56 and you can use yous standard AR 15 mags its a no brainer if you are already in the AR platform and an added plus is you can just chop off your split necks and turn them into 300 brass,whats not to like? A 220 gn bullet with a suppressor and you have a perfect round for close range work with near total silence.I love my AK and SKS but having an extra 30 cal upper in the AR tote bad just makes sense and adds zero hassle.

    mf7 – Lately i used to be so lacking in $$ and debits were eating me from all sides. that was Right Until i decided to generate money.. on the INTERNET.

    “Why? Because it’s not particularly good as distances stretch past a couple hundred yards, and when I stuff a cartridge into a rifle, I want it to act, well, rifle-like. ”

    I’d like to ask…How long is your barrel? If you’re shooting out of a 16″ carbine length barrel, and expect rifle-like performance, then, shame on you sir.

    • StupidFast45

      Some barrels are naturally longer than others. It’s not the length of your “Barrel”, it’s what you can do with it.

      • flyingvlover

        lmao ;-)

    • Marine Guest

      16″ barrel is good enough out to 500yd. I used to qualify every year with a 16″ on my M16A2 at the rifle range (with open sights, cogs and holo sights had to come off for quals). Every marine knows that 500 in prone position (no bipod) is very doable if you follow the fundamentals. The .300 hits much harder than 5.56 and nobody is engaging anyone at 500yd with that small of a rifle anyway. we always used .308 or .50 for anything beyond 400 if we had more than a moments notice.

    Please stop with the .300, sammi specs it. 300blk or 300 blackout.

  • Sandman

    I have used both in thearter, The AR platforn in a few offerings, and the AK as a Back -up; with the sole exception of reliability in the nastiest of filthy situations, the AK-47 in any incarnation (PKM, AKS, AKM, Dragonov, AK-47/74) is horribly inaccurate except to spray and pray. You can coax sub-MOA if youstand in front of a 10×10 sheet of paper (from 5 feet) (Okay I jest, but not far from the truth). The looser tolerences are woefully inaccurate by design. The .300 BLK is accurate by design, from the weapon, to the cartridge. Remember, it is not the first shot fired, or even the most rounds fired that wins a gun-fight, it is the first accurately fired shot that wins!
    That being said, except for a single raid I can remember vividly, the 5.56mm round performed to it’s intended purpose. Can’t complain, nothing I ever shot with it, ever got back up.
    It is all about hitting the apricot, the peach pit, well, you know…

    • zipper

      Have you tried an AK-74? It will shoot rings around an AK-47, and has HALF the recoil of an AR in 5.56. Works for me.

      • Sandman

        My Good Zipper, please re-read the post, that is a yes. The 5.45mm cartridge was place into service by WARSAW Pact countries during my nearly 30 years of service. This is experience talking, not taking out of the side of my neck… But there are always folks that will favor the AK in any incarnation, and that is cool, (gentlemen on my own team favored it, but not for accuracy), it’s just not nealy as accurate as an AR platform.
        No amount of wishing will make is so either. Just the Facts, not embelishing, just fats.
