Daniel Defense 300 BLK Ammo

DD Ammo

Daniel Defense announced a new line of ammunition and the first load it will offer in that line. After picking a 300 BLK load to launch the line, Daniel Defense said it will expand the First Choice line of ammo to include other rifle calibers including the 5.56 NATO and 7.62×51 cartridges.

The new 300 BLK load is a subsonic round that uses a 220 grain Lapua Secnar-L Open Tip Match (OTM) bullet loaded to 1,098 fps from a 16″ barrel. The company states that the round clocks in at 1,036 fps from a 10.3″ barrel. The cases are brass and they use Boxer type primers.

Daniel Defense advised that all ammunition goes through a detailed inspection prior to shipping. Rounds are checked to ensure they meet critical dimensions standards, and advised that it will not ship any product that isn’t perfect.

The suggested retail price of the ammo is $50 per box of 30 rounds. Currently, the ammunition is only available through Daniel Defense, though I would imagine the company would be happy to have its ammo sold through big box stores, local dealers and the big online shops. Shipping is free with the purchase of four or more boxes.

This new ammo should match nicely with the company’s Integrally Suppressed Rifle and other AR accessories it introduced this year.

    People in Denver should be aware that this ammo will be supersonic out of the 16″ barrel, at their elevation.

  • TheNotoriousIUD

    I only but handmade craft ammo from a skilled local artisan who uses free range powder.

    • ostiariusalpha

      Hmm, but is the powder raised on pesticide-free & GMO-free nitrocellulose?

      • TheNotoriousIUD

        Of course, im not a barbarian.

  • Tyler McCommon

    $50 a box of 30rds. $1.6 a shot! Man what a deal! Almost as affordable as their AR15’s!!

      I have one, a DDM4V5, great accurate rifle. Worth every penny.

    • Ryobiwankenobi

      When the bullet itself costs around 40 cents(US) per round it’s understandable why their ammo costs so much. Match grade bullets are great but maybe not for hunting or defense.

        Or even for the 300 Blackout, generally. It is possible to make 300 Blackout rifles accurate, but they generally lack precision and run out of steam quickly (not complaining, it’s just the nature of the beast as they weren’t designed for long-range precision). So, using mondo-expensive, ultra-match grade bullets are overkill and a waste.

        I like the Blackout, I’ve invested in it. It’s the reason why I got into SBR’s and suppressors. However, people mostly overstate it’s capabilities or “don’t get it”. I’ll stop here before I start to ramble.

    I’ve seen this pop up on a couple other sites. I don’t know why DD is saying that this is a good choice for Home/Self-Defense (says right on their website). A heavy subsonic round that will offer no expansion and has high sectional density to ensure over-penetration!

      Sierra Match King OTM is about the last thing I’d pick.

      • JumpIf NotZero

        Not for barrier-blind it’s not 🙂

        • Sianmink

          I mean if you need to shoot THROUGH your house to hit the bad guy, okay.

    • Beju

      Because 9x19mm ball makes through-and-through holes that are 1.2mm too large in diameter for my liking.

  • Nocternus

    I don’t really understand the attraction to 300 Blackout it has roughly the same performance as 7.62X39 and is considerably more expensive per round. I understand the feeding issues and the need for a curved magazine with 7.62X39 but just to get a different magazine shape doesn’t seem worth the price of the ammo.

    • Anonymoose

      Good luck getting 7.62×39 subs or pouches for 7.62×39 AR mags. You also don’t have to use a special bolt instead of the standard 5.56 bolt.

      • Nocternus

        300 Blackout is literally twice the price of 7.62X39 it will not take long on the range for the price of ammo to pay for itself given the cost of a different BCG or difficulty finding pouches for your plate carier. I have a no bastard caliber rule for my gun safe.

  • Nick

    The choice of bullet seems awful expensive. Plenty have used Hornady’s 208 or Nosler’s custom competition 220’s. Surely they’d cost considerably less than a premium long range match bullet.

    Regardless, at $1.60 per shot, I don’t expect them to be flying off the shelves.
