Creedmoor 9mm Ammo Now Available with Shell Shock NAS3 Cases

Creedmoor 9mm

Creedmoor Ammunition is now manufacturing a 9mm load using the new Shell Shock NAS³ cases. This handgun load uses a Hornady 124 grain XTP bullet loaded to +P pressures to produce a muzzle velocity of 1,175 fps and 380 foot pounds of energy.

These rounds are being sold in packages of 50 rounds, and come in a reusable MTM translucent plastic case. The price for a single box is $29.50, but the company offers significant discounts on quantities of five or more boxes. For what is intended as a self defense load, the pricing seems reasonable. The MTM case is a nice extra.

By way of comparison, Creedmoor Ammunition also makes the same load with a traditional brass case. Those loads are sold in 20 count boxes for $12.20 each (with discounts for larger quantities.) This works out to be $30.50/50 – or a full $1/box more than the load with the Shell Shock cases. Oh, there is no MTM container with the brass cased version of the ammo.

On the surface, it would appear that Shell Shock is delivering on its claim of making less expensive cases.

If you are not familiar with the Shell Shock NAS³ case, it is a two piece design that uses a nickel alloy body with a nickel plated aluminum head. The parts are joined together by a proprietary machining technology that creates a high pressure compression joint.

According to Shell Shock, the resulting case is both lighter and stronger than conventional brass cases. The Shell Shock NAS³ cases are pressure tested to 65,000 psi – well above the SAAMI rating of 38,500 psi for the 9mm +P.

The Shell Shock NAS³ cases are reloadable, but require the use of a special resizing and flaring die. These dies are available from Shell Shock. Additionally, they use standard threading and have been tested with a range of popular presses including those from Dillon, Lee and Hornady.

    Personally, I’d rather have someone else try these out first, because if there’s anything to be learned from pretty much any industry in general, it’s that you should let someone else be the guinea pig with new products.

      ah the early adoption penalty, the early adopters pay the most up front, do all the bug finding, and spent the most time frigging around, and yet without them we would have no new products whatsoever, aint that a fun place to be

    Watered down velocity in a goofball case sold as “carry ammo”?

    They can keep it.

    • Christian Hedegaard-Schou

      1175fps isn’t “Watered down” for a 124gr JHP.

      About the average max load for that combo is around 1050fps.

      • Speer 124gr +P Gold Dot is specced at 1,220 fps.

        • Christian Hedegaard-Schou

          Still doesn’t make 1175fps “watered down”.

          • Frankly both loads are a bit slow; at 38kpsi spec for 9mm +p, you can hit 1250fps w/ 124gr out of a 4″ barrel with the right powder usage.

          • raz-0

            It’s not hitting the industry average, and for all the claims they made of being able to handle way more pressure than traditional cases, it’s deserving of catching some flak.

      • Frank Grimes

        If a 124gr +P load isn’t hitting 1200fps, it’s watered down.

        I load the 124gr XTP to 1275fps, they can sell all their crap that barely exits the barrel to all the hillbillys with Keltecs, no real shooter would waste money on this crap.

        • Christian Hedegaard-Schou

          Sorry, what’s the SAAMI spec for a 124JHP 9mm +P again?

          Just because YOU reload to a certain velocity doesn’t make 1175fps “watered down”, especially when standard load data from powder manufacturers shows max averages lower than 1175fps.

          • Frank Grimes

            124gr +P Gold Dot is THE standard for factory carry ammo.

            And as stated, that’s spec’d for 1220fps.

          • Frank Grimes

            Why are you comparing load data for non-+P loads to +P loads?

            In terms of what a proper velocity is for 124gr +P is, this ammo is watered down.

          • Norman

            SAAMI rates the pressure, not velocity. Just searching Midway, I found 1200 fps +P 9mm sold by Winchester, Hornady, Speer, and Black Hills ammo. Atomic Ammunition even claimed 1200 fps for their +P 9mm.

        • RocketScientist

          Am I reading this wrong? You’re saying 1200 fps is “acceptable” for 124gr +P, and that you load your handloads to 1275 fps (no comment as the liklihood of those being SAAMI approved pressures). And youre complaining that at 1175, these are “watered down” and will “barely exit the barrel”? How much of a difference do you think 25 fps is going to make??? thats about 2% difference in velocity, which equates to a difference of about 16 ft-lbf of kinetic energy if I’ve done my math right. For the sake of context, if you dropped a can of beer from a 2nd story balcony, it’ll hit the ground with about 16 ft-lbf of kinetic energy. And this differentiates acceptable performance and completely useless in your mind?

          • Frank Grimes

            My point is that nearly all the other major manufacturers meet 1200fps as a minimum so, in terms of what’s available on the market, this ammo is watered down and if they didn’t put enough effort into meeting the standard set by other manufacturers, where else did they skimp?

            And my handloads only need to work fine in my gun I don’t need to meet a standard, but it’s fine because my handloads have less pressure signs than Corbon and they’re loaded with less powder than Underwood with the same powder Underwood uses in 9×19 and I’ve shot over a thousand, they’re fine.

            I’m also not offering them for sale, so aside from what velocity they meet with this particular bullet, they’re not otherwise comparable to the ammo in this article.

    Why don’t they just make nickel plated aluminum cases? Sometimes things are made too complicated in order to reinvent them. If someone wants to reload they can just use brass cased ammo.

  • 22winmag

    In my opinion there is Liberty Civil Defense ammo and then there is everything else. 1,900fps in 9mm and 2400fps in 10mm. The trolls who rip Liberty are just reinforcing what I already know… it’s the best.

    • iksnilol

      That’s mighty fast, but with how heavy bullets?

      • In 9mm, Liberty uses a 50 grain bullet. I’ve tested a bunch of this stuff in a range of firearms. As a reference, the G19 runs about 2,025 – 2,050 fps @ 10 ft over my chronograph.

        The Liberty load gets very interesting out of a carbine, with a 50 grain bullet running around 2,500 fps from a 16″ barrel.

    I wanna load some of these cases to 55,000+ psi. You know for science. These cases in the .40 Smith & Wesson could easily eclipse the Underwood 10mm loadings. I’m interested to see where these go.
