[QUOTE="jon.henry755, post: 623984, member: 29115"] Hi Twanger, While it's an interesting statistic, it only applies to bullets or guns. It has no relevance in the field of archery unless you wanted to compare the results to other bows or crossbows. The reason is because bullets don't have razor sharp points that cut and slice their way through anything they hit. The only measurement that is of a major significance for an arrow is K.E. (Kinetic Energy). This can be calculated using the following formula: Kinetic Energy = Weight x Velocity / 2 x Acceleration of Gravity Here is a simple chart which depicts the amount of K.E. needed to efficiently penetrate some common game animals: [B]Kinetic Energy Hunting Usage [/B] [B][COLOR=#660000][FONT="]< 25 ft. lbs.[/FONT][/COLOR][/B] [B][COLOR=#000066][FONT="]Small Game (rabbit, groundhog, etc.)[/FONT][/COLOR][/B] [B][COLOR=#660000][FONT="]25-41 ft. lbs.[/FONT][/COLOR][/B] [B][COLOR=#000066][FONT="]Medium Game (deer, antelope, etc.)[/FONT][/COLOR][/B] [B][COLOR=#660000][FONT="]42-65 ft. lbs.[/FONT][/COLOR][/B][B][COLOR=#660000][FONT="] [/FONT][/COLOR][/B][B][COLOR=#000066][FONT="]Large Game (elk, black bear, wild boar, etc.)[/FONT][/COLOR][/B][B][COLOR=#660000][FONT="] [/FONT][/COLOR][/B][B][COLOR=#660000][FONT="]> 65 ft. lbs.[/FONT][/COLOR][/B][B][COLOR=#660000][FONT="] [/FONT][/COLOR][/B][B][COLOR=#000066][FONT="]Toughest Game (Cape Buffalo, Grizzly, etc.)[/FONT][/COLOR][/B] The PSE TAC15 with a 100 grain broadhead is generating approximately 154 foot pounds of K.E., so way over powered for its intended job and will likely blow straight through anything your ever going to hit with it.
