The Seismic Raging Bull Stampede™ has been engineered to provide more torque at the end of the pattern than has ever been seen in a Seismic ball.
The Horn Core has been their most popular core to date. Matching this core with the new SF79 Coverstock, the Stampede™ provides you with the same stable roll which sets up for an strong back end move. This Core/Cover combination is designed for maximizing carry percentage on high scoring lanes. Video of the new Seismic Stampede
