The faster an already aeroballistically inefficient lead pellet is fired, the quicker it slows. A No. 7 ½ pellet that starts out at 1,295 fps has slowed to 705 fps by the time it has traveled 40 yards. But that same pellet fired at 1,135 fps has only slowed to 650 fps at 40 yards. True, the faster pellet always remains faster. However, the faster pellet carries only an additional 0.4 ft.-lb. at 20 yards and 0.2 ft.-lb. at 40 yards than the slower pellet. Shoot a larger pellet if additional pellet energy is needed. Out at 40 yards, a No. 5 pellet fired at 1,200 fps carries more than twice the energy (3.1 ft.-lb.) as a No. 7 ½ pellet fired at 1,330 fps (1.3 ft.-lb.).
