Research & Development


Seismicâ„¢ High Mass Ammo is the first +M ammunition. The ability of a projectile to penetrate and damage a target is dependent on the momentum behind it. The formula for momentum is: p (momentum) = m (mass) times v (velocity). The greater the mass, the more momentum it generates. We realize that take down power and terminal ballistics are a complex, debatable subject. We believe balancing projectile mass with optimized bullet construction and velocity gives the best combination for down range results.

Shipping will be delayed on all orders until Jan 25th after we return from Shot Show.
