PowerBelt ELR Bullets were specially designed for CVA's PARAMOUNT rifle, but can provide superior long-range performance in any .45 caliber muzzleloader. In testing with the CVA PARAMOUNT, using the the maximum recommended "supermagnum" charge of Blackhorn 209 propellant, ELR bullets achieved muzzle velocities of 2560 in .45 caliber. Critical to the ELR's long-range potential is the high ballistic coefficient as compared to other muzzleloading projectiles. Due to their longer length and aggressively tapered shape, the ELRs deliver .333 BC in .45 Internally, the ELR is similar in concept to the PowerBelt AeroLite bullet, incorporating a large hollow point cavity which eliminates weight from the core, allowing that weight to be used to lengthen the bullet. This hollow core is filled by the tail of the polycarbonate ballistic tip, which offsets the tendency of the bullet to expand too rapidly. Optimal performance of the ELR will be achieved using "magnum" or "super-magnum" propellant charges.
