Description Ultra thin jacket mouth assures violent expansion at either end of the velocity scale. Uniform, gradual thickening of the jacket wall at the bullet's mid-section keeps the bullet together until impact at any velocity. Pure lead core is form-fitted to the core cavity to eliminate possible imbalance and erratic flight caused by air pockets. Heavy jacket base prevents bullet deformation. 6mm Caliber .243 Diameter.
