as you become more versed in firearms youll eventually find these calculators more and more useful.
if your selecting a bullet for hunting big game Id suggest a minimum of 25 caliber and a minimum sectional density of .240 usually works fairly well, and try to keep rifle velocity at impact over 1600fps on any bullet under 200 grain weight for consistent results, and keeping the impact energy at at least 650 ft lbs for deer and 800 ft lbs for elk helps, obviously increasing the velocity, bullet weight and energy impact levels tends to make the projectiles impact more effective, but its exact shot placement,with a consistently dependable bullet design, placed into the vital organs thats key to consistently getting good results
