SHOT Show 2019: Seismic High Mass Ammunition

Published on February 12, 2019
Duration: 7:01

This entry details Seismic Ammo's High Mass Ammunition line, focusing on their significantly heavier projectiles for 9mm, .45 ACP, and 12 Gauge. The analysis, informed by an expert assessment of authority and knowledge, covers the ballistics, case technology (Shell Shock Technologies), and recoil management strategies employed. It highlights the impressive engineering required to achieve reliable cycling with these heavy loads in standard firearms.

Quick Summary

Seismic High Mass Ammunition utilizes significantly heavier projectiles, like a 185-grain 9mm subsonic round, to maximize momentum. They employ slow-burning powders for manageable 'push' recoil and Shell Shock Technologies' two-piece cases for pressure containment and magnetic retrieval, ensuring reliable cycling in standard firearms.

Frequently Asked Questions

What is Seismic High Mass Ammunition?

Seismic High Mass Ammunition features significantly heavier projectiles than standard loads, such as a 185-grain 9mm subsonic round. The goal is to maximize projectile mass within standard cartridge dimensions for increased momentum and 'knockout power'.

How does Seismic manage recoil with heavier bullets?

Seismic uses slow-burning powders to manage chamber pressures, resulting in a 'push' recoil impulse rather than a sharp 'snap.' This engineering allows for felt recoil comparable to standard ammunition, even with much heavier projectiles.

What is the Shell Shock Technologies case?

Shell Shock Technologies provides a two-piece ammunition case with stainless steel walls and an aluminum head. This design helps contain high pressures and allows for magnetic retrieval of spent casings, a unique feature for ammunition.

Is Seismic High Mass Ammunition reliable?

Yes, Seismic has tested its High Mass rounds across various platforms, including Hi-Points and select-fire weapons, ensuring reliability despite the unusual projectile weight and length. The engineering focuses on consistent cycling in standard firearms.
