Westport, Conn. ( – Shell Shock Technologies, LLC., an early-stage technology and manufacturing company focused on developing innovative case technologies for the ammunition industry, announces that Seismic™ Ammo has introduced its 185gr 9mm round featuring Shell Shock Technologies’ revolutionary NAS3 casings.

Seismic’s QuakeMaker™ +M 9mm NATO bullets are heavier and deliver far greater momentum than any other 9mm. At subsonic velocities, they’re ideal for suppressors. The QuakeMaker +M projectile is 160 percent the weight of a standard 9mm bullet. It is available in a 21 Round Bonus Pack ($29.99), 21 Round Bonus Pack Full Case ($359.88), and 21 Round Bonus Pack Half Case ($179.94).

“Seismic Ammo is taking conventional ammunition in a different direction. We believe a projectile with more mass traveling at subsonic velocities (900 – 1,000 fps depending on the barrel length) is more effective than a lighter weight projectile traveling at a higher speed,” said Matt Wilkes, Chief Operating Officer of Seismic Ammo.

“We are thrilled and honored to have our innovative NAS3 casings be a part of Seismic Ammo’s take on a heavier 9mm projectile,” said Craig Knight, CEO of Shell Shock Technologies.

About Shell Shock’s NAS3 Cases:

Shell Shock’s NAS3 9mm cases are 50 percent lighter than brass cases, offer greater lubricity, and will not abrade, clog, foul, wear-out, or damage breach and ejector mechanisms. The cases offer greater corrosion resistance, tensile strength (2x stronger), and elasticity in comparison to brass. NAS3 cases will not split, chip, crack, or grow (stretch).  They are fully reloadable (using S3 Reload dies) and can be reloaded many more times than brass cases. NAS3 cases have been tested successfully by customers to pressures over 70k psi. NAS3 cases can be picked up with a magnet. The head can be colored for branding purposes and easy load identification.

NAS3 is “Best in Class” for maintaining consistent velocity between rounds. In an independent test performed by H.P. White Laboratory (a major munitions testing facility), rounds fired using NAS3 cases achieved a velocity standard deviation of 0.093 FPS (124-grain FMJ bullet, 4.2 grains Titegroup powder, 10 rounds, extreme variation 3fps).

So we’re starting to swing back to heavy bullets moving slower are more effective than light bullets moving faster but this time we want to make the small bullets heavy instead of admitting the big heavy bullets we already have are more effective?

Alrighty then.

Yeah….so now we’re back to a .45!


The idea doesn’t seem too bad, but someone on their marketing team really failed since they don’t understand math. If a standard weight 9mm is 115 grains, then 185 grains is only 60% more mass, not 160% more.


So, a 40 cal. bullet equivalent for a 9mm gun…… ok


Where’s my 200gr .38 spcl for my Snubbies?????


160%??? No such thing, You can only have 100% of anything.


they might mean 1.6 times the weight.


Keep digging. You and Jim W should either not comment on math or get an advisor before you comment.

Darn auto correct…”there” not “their”…

American Patriot

Must be the new math your using….Based off a 115 gr it would only be 60.8% heavier!

But than they say biden won the election & boys can be girls, so I guess anything can be what you wish…..


Yeah you sure proved to be as smart as Ex-president Trump. If something equals 100% of the weight of another object, they would be the same weight. These rounds weigh 60% MORE!! What is 100+ 60? I know you are a Trump supporter but I know you have to of passed the 1st grade.. let me help you, 160!!!!

Your welcome, 1st grade math lesson brought to you by a Biden supporter.


Just curious what makes you a Biden supporter?
Were you always a Biden supporter or a lifelong Democrat that just supports whoever is running or nominated?
Was it ” I can’t stand Trump so anyone else has my vote”
Do you support Biden’s “gun control” agenda?



Your “math” is jacked up. One hundred and sixty percent of 115gr is 184.0gr. I guess they rounded up. In any case why would one buy from a “company” that is unfindable. And they are supposedly located here in the OKC area. I think the heaviest bullet I have loaded in 9mm is 160gr. They required the Lee crimping die with the carbide ring to assure proper chamber fit and as a consequence the rear portion of the bullet (cast lead) is sized down a little. Nothing gained over 150gr bullets as far as I was concerned. Much ado about… Read more »


115 x 1.6 = 184

The math is right, I don’t know about this company’s quality or reputation .

Actually the 185 gr bullets are 155.46% heavier than traditional 119 gr 9mm bullets. Or their is a 55.46% difference in billet weight…
