Can anyone tell me the approximate remaining velocity and FPE of a HN 14.66 gr. .22 pellet at 150 yards. Use 800 FPS muzzle velocity and 5000 feet above sea level as a baseline.
You can use online ballistics calculators or mobile apps such as Strelok or Chairgun to get fairly precise answers. Strelok is my recommendation, it generates customizable data tables for ballistics over predefined distance intervals.
