Designed with a plating technology, a bullet shape and a gas check design that combine to make the Platinum Series the best performing PowerBelt ever. PowerBelt Platinums are plated using a proprietary process that produces a harder exterior surface than standard copper plating. This harder plating results in reduced resistance as the bullet travels down the bore, producing faster, more consistent velocities to improve both trajectory and accuracy. PowerBelt Platinums also deliver an improved ballistic coefficient by utilizing a more aggressive bullet taper design. Not only does the taper provide for a more aerodynamic flight, it also helps control the rate of expansion - regardless of powder charge or distance the bullet travels.
