The Shock Wave is a new spire point bullet with a polymer tip specially designed as a muzzleloading sabot bullet, not a conventional pistol bullet converted to a muzzleloading projectile. T/C's Shock Wave incorporates modern technology previously only applied to centerfire rifle bullets. The polymer tip of the Shock Wave bullet does double duty; it increases the ballistic coefficient for sustained high velocity down range and it punches into the pocket to open up the nose cone for fast expansion. The Shock Wave has a harder lead core with walls interlocked with the jacket for maximum weight retention and expansion. 15 pack
