PowerBelt ELR Bullets were specially designed for CVA's Paramount rifle, but can provide superior long-range performance in any .45 caliber muzzleloader with a twist rate of 1:24 or faster. In testing with the PARAMOUNT, using the recommended "super-magnum" charge of 140 grains by-volume of Blackhorn propellant, ELR bullets achieved muzzle velocities in excess of 2200 fps. Designed for Maximum Long-Range Performance on Medium to Heavy Game. (Deer, Antelope, Elk)Designed for Maximum Long-Range Performance on Medium to Heavy Game. (Deer, Antelope, Elk). Polycarbonate tip preserves aerodynamic integrity and prevents premature expansion Smooth plated finish reduces standard deviation between shots for superior accuracy Larger diameter gas check for tight seal Larger hollow point cavity reduces weight and maximizes internal expansion Longer Length combined with aggressively tapered shape Flutes in gas check make it easier to load Scores inside gas check allow positive release when bullet exits barrel
