300 AAC Blackout is a popular caliber, but that popularity comes at a price. Namely about $0.50/round. The problem is classic supply and demand, and in this case the demand is far outpacing the supply. With the first production run of the .300 BLK based civilian MCX rifles in full swing, SIG SAUER is leveraging their new ammunition manufacturing plant to try and give their customers a little assistance and bring down the price. Needless to say we’ll be getting our hands on some of their ammo shortly for testing purposes. And an MCX. And an MPX. Stay tuned, and make the jump for the press release.

Newington, NH (January 12, 2015) – SIG SAUER, Inc. is pleased to introduce 300 Blackout Elite Performance Ammunition Match Grade Centerfire Cartridges, the company’s first rifle ammunition product. Designed for the AR-15 platform, this subsonic round features a 220gr Open Tip Match (OTM) bullet with the SIG SAUER proprietary lead/alloy core for improved accuracy. This low-recoil cartridge is ideal for use with a silencer, which greatly reduces sound signature and muzzle flash, making it a favorite among target shooters who want to protect their hearing and tactical shooters who want to minimize noise and flash signatures. Additionally, a significant number of modern sporting rifle hunters also favor this cartridge for limited hunting applications.

“The subsonic, 220-grain 300 Blackout is fun to shoot, especially using a silencer, and extremely popular with those who want reduced sound and muzzle flash,” said Bud Fini, vice president of marketing for SIG SAUER. “Fans of the 300 Blackout also appreciate the convenience of being able to use standard 5.56 NATO AR magazines with 300 Blackout rounds without a reduction in capacity. And, if they don’t already own a modern sporting rifle chambered in 300 Blackout, all they have to do is change the uppers of their AR-15 to convert.”

Additional offerings in Elite Performance rifle ammunition will be introduced throughout 2015, including a supersonic load for the 300 Blackout.

  1. More supply is great, but not holding my breath for this ammo to priced anywhere but at the top of the market

  2. Love me some 300 blk. Need actions like this to change the supply vs demand equation. Hoping we can see prices come down and availability increase in 2015.

  3. When we test, puhleeze show us some expansion tests, other than Lehigh I still have not seen a 220 sub that expanded at all, despite lotsa claims.

    • I keep hoping someone makes a handgun-ballistics flavored 220-240gr 300blk projectile. Something actually designed to expand at moderate velocities. I’ve had very limited success with the 208Gr Amax tumbling but that has been with loads right at 1100fps and at basically point blank range – nothing I would use to hunt and those loads aren’t all that quiet anyways. The 225Gr Hornady BTHP is the most accurate subsonic load for me, but there are no terminal effects.

    • I haven’t seen anything else either, but I used a Lehigh Defense 194gr subsonic to take my one and only deer this year, and it worked exactly as advertised. The exit wound was a 2″ cross-shaped hole, and she went down like a sack of bricks.

  4. Less “Match Grade” more “Sub-Sonic” plinking/blasting plx….

    And while I’m wishing for the nonexistent, a shipping date for the MPX.

  5. All any company needs to do is start making bullets for .300. People will gladly load their own if the bullets are cheap enough.

    • If you just need plinking ammo you can use cheap 147gr .308 pulls. The 300BLk reloading options have gotten pretty nice lately, with Sierra’s cheap 110hp and Barnes 110 making pretty nice high velocity loads.

  6. I’ve never had an issue finding 300 BLK ammo. There always seems to be a bunch in my storage room, especially right after I load a big pile of it.
    Now 300 BLK cases, those are hard to find. They blend in too well with the rest of the cases on the range floor.

  7. So now that we’re talking 300 BLK…

    Been researching 300 BLK piston uppers. Somehow I have it in my head that this is the holy grail of sorts (a 300 BLK piston-operated pistol, with sig brace).

    My conclusion has led me to believe that perhaps 300 BLK does not have enough ‘ooomph’ to drive a piston system well.

    LWRC, who have never made a DI gun, made their first one for 300 BLK (what does that tell you)
    SIG – Same damn thing. DI
    Daniel Defense – DI

    Now I see PWS has their MK109, but it’s not adjustable and reports seem to indicate it’s a bit under-gassed. Would work fine if you are always suppressed.

    Adams Arms has their new XLP 4x adjustable low profile block (and uppers), but… I lost a little confidence in the fact that they released their new shorty 300 BLK upper with a Samson Evo Free float rail that essentially prevents you from actually being able to adjust the gas system without taking off the tube (DOH, I saw this from day one of the announcement). Apparently they are working on that now.

    Is that going to be the winner? A short stroke adjustable (pistol length) piston with low mass BCG?

    Then I start to wonder… Is that really going to be better than DI. Extra weight up front, definitely reduction in accuracy, and un-proven, non-standardized operating system and BCG. Too many unknowns.

    Maybe 300 BLK is just destined to remain DI only. And why am I so hung up on the potential of a good short barreled piston anyway? This all stems from an issue I had with my MPW (BCG/gas key binding on the gas tube). Maybe I should just wait to see if AAC can make me whole again. Damn if that thing is not sub MOA accurate and kicks like a pussy cat. Man, I hope I can get my confidence back in that system, because it really is all that and a bag of chips – when it actually cycles.

    • Check out the ARAK-21…piston AR in 300 BLK with adjustable gas. Boom goes the dynamite. Mine works perfectly using both supers or sub’s both suppressed or unsuppressed. Zero malfunctions thus far.

  8. The more the merrier! But only father time can bring down ammo prices. Huge military contracts can shorten the timeframe though.

  9. Buy an H&R Handi-Rifle. It’s single shot setup will slow your consumption. Mine wears a Leupold and a Cerakote finish. Overkill? Absolutely!

  10. The problem is cost of ammo from the get-go. If it wasn’t $1/rd people would be lining up to buy them, especially if they could get pricing near 5.56. I’ll agree with other comments that manufacturers need to quit making all of this Match/Super Great ammo and just throw some stuff together that will make using those weapons a little easier on the wallet.

  11. Man, TTAG really laps up the Sig kool-aid. First we get reports of a mid level AR priced MPX, and now it’s cheap .300blk ammo. Come on guys, when has Sig ever made anything inexpensive? Hell, I’m not anti-Sig. I’ve got a 1911, and P226 Scorpion, but neither one of them was Glock, or S&W priced.

  12. I’ve loaded a few thousand rounds, and shot several hundred of my home cooked 300blk. Cutting off and swaging once fired LC brass keeps my cost at 25 cent / round.
