[QUOTE="highcountry74, post: 2476376, member: 10155"] there is a formula you can use to calculate your crossbows kinetic energy velocity x velocity x arrow weight= divided by 450.340= i shoot a 497 grain arrow @261 fps and i get 75.2 pounds of energy.when i shoot carbon i get lower energy numbers.so if youve ever wondered how much energy your shootin there is the equasion to let ya know.and i have also found when i use my string cocker it tightens my groups up quite a bit.i started shootin last night out to 40 yards and with a rope cocker @ 40 yards i can wrap my fingers around 3 bolts.cocking by hand i cant.what a differance a rope cocker makes.
