PowerBelt Bullets AC1553AT Platinum 50 Cal AeroTip 270 GR 15 Per Box. The PowerBelt Platinum AeroTip Bullets utilize an advanced plating technology, a more aggressive bullet shape and a fluted gas check design that combine to make the Platinum Series the best performing high velocity PowerBelt ever. The proprietary plating process produces a smoother, more uniform surface that reduces the standard deviation between shots and reduced resistance as the bullet travels down the bore for faster, more consistent velocities to improve both trajectory and accuracy. The more aggressive bullet taper design delivers an improved ballistic coefficient, more aerodynamic flight, and helps control the rate of expansion - regardless of powder charge or or bullet velocity on impact. PowerBelt Platinums feature a fluted gas check, allowing the check to be sized larger than that of a standard PowerBelt, while still being just as easy to load. The larger diameter, fluted gas check fits more tightly and and is reinforced to better withstand magnum pressures, improving both velocity and accuracy.
