One of the more interesting entries into the ammunition market at SHOTShow 2019 is the Quakemaker +M 185-grain 9 mm round, from Seismic HighMass Ammunition. From Seismic’s webpage:
“Introducing the first in a line of unbelievably massive rounds, theSeismic Ammo Quakemaker in 9 mm. Weighing in at an incredible 185 grains,Quakemaker +M ammo gives your 9 mm pistol more momentum then ANY other9 mm round in existence and it does so while staying subsonic (950 fps),so it's perfect for suppressed weapons.”
We took a minute to both shoot the QuakeMaker +M round, and also visitthe company's booth to ask some questions about the round itself. The QuakeMaker+M was born from a desire to make a more reliable subsonic round, thatwas guaranteed to stay subsonic. The direction that Seismic took, was anincredibly heavy-for-caliber round loaded into a novel, two-piece ShellShock case. The Shell Shock case features a nickel alloy stainlesssteel “case” portion and a red anodized aluminum base.
The 185-grain 9 mm +Mround is listed as having a muzzle velocity of 950 FPS out of a 4.5-inchGlock G17 Gen 3. Seismic currently has its ammo out for testing at anindependent lab, but is confident that they are achieving this velocitywhile maintain a safe chamber pressure.
As far as the terminal effect on target goes, the only testing that iscurrently available is Seismic’s own in-house tests, which wereconducted using Clear Ballistic Gel, shot bare with no test protocol.Expansion appears to be on par with other popular 9 mm rounds, and the Seismic Ammo teamconveyed that they were seeing just a hair under 16 inches of penetration intheir bare gel shoots.
It should be very interesting to see how this newammo fares when it is able to be independently tested and run througheither the FBI Heavy Clothing, or Four Layer Denim test protocols. Formore information visitwww.seismicammo.com.
