The only other times I have really used energy calculations were for IPSC, and to make sure my handgun makes the required power to hunt deer in good ol VA during the rifle season.
how to calculate energy in your head.
Re: how to calculate energy in your head.
Just to add a bit in regard to the use of energy calculation of a specific let's say projectile and it's intended target. For those of us who like to hunt small to medium sized game and varmints with air rifles, we do actually use the energy calculations for our projectiles to ensure we are producing enough energy to humanely take down the critter we are shooting at. Basic example 1 ft.lb of energy per lb of animal is generally considered the very minimum. Heck the Brits have been regulated to 12 ft.lbs for their air rifles for decades, and regularly take rabbit and the occasional squirrel out to the 40-50 yard range. Here we tend to lean more in the range of at least 20ft.lbs for the same game at the 40-50 yard mark, and keep track of our trajectory curve, and the retained energy of those projectiles at distance. We have also found that just like hunting dangerous game most would choose a solid, at air gun velocities and energy, hollow points rarely expand, so solids / domes are the better choice, and tend to retain their energy. Sorry that was overly long all, I am a fairly avid air gun hunter, and take these things into consideration. I however do all of my energy calculations, trajectory charting, and other variables when sighting the gun in so I know where to aim when I'm out hunting those tree rats.
