SHOT Show 2019: Seismic High Mass Ammunition

Published on February 12, 2019
Duration: 7:01

Seismic High Mass Ammunition offers significantly heavier projectiles for 9mm, .45 ACP, and 12 Gauge, aiming to increase momentum and impact. Despite the increased mass, they utilize slow-burning powders and innovative Shell Shock Technologies cases to manage pressure and recoil, resulting in a surprisingly manageable impulse. The company has demonstrated reliability across various firearm platforms, validating their 'heavy hits harder' philosophy.

Quick Summary

Seismic High Mass Ammunition uses significantly heavier projectiles (e.g., 185gr 9mm) and Shell Shock Technologies' unique two-piece cases. Slow-burning powders manage pressure for a manageable 'push' recoil, ensuring reliability across various firearms.

Frequently Asked Questions

What makes Seismic High Mass Ammunition different from standard loads?

Seismic focuses on significantly heavier projectiles, like an 185-grain 9mm instead of typical 115-147gr. Their philosophy is that 'heavy hits harder,' aiming for increased momentum and impact, while using specialized powders and cases to manage recoil and pressure.

How does Seismic manage recoil with heavier bullets?

They utilize slow-burning powders to keep chamber pressures manageable. This results in a smoother 'push' recoil impulse rather than a sharp 'snap,' making it surprisingly comparable to standard loads during testing.

What is the Shell Shock Technologies case used by Seismic?

Seismic employs a two-piece case design from Shell Shock Technologies, featuring stainless steel walls and an aluminum head. This construction helps contain high pressures effectively, especially with the reduced internal volume from heavy bullets.

Is Seismic High Mass Ammunition reliable in different firearms?

Yes, Seismic has tested their ammunition across various platforms, including Hi-Points and select-fire weapons. The company ensures reliability despite the unusual projectile weight and length, meeting NATO-spec pressures for their 9mm loads.
