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.
