Anything comparable to .243 or above should have sufficient power to take any size hog at any reasonable distance with good shot placement. In Hawaii, the rule is anything greater than 1,200 ft/lbs ME, so .223's are legal. I personally use a 7mm rem mag on hogs, but my cousin uses a 30-30 and my coworker uses a .270.

Choose your crossbow to shoot your hunting arrow with an initial velocity of a minimum of 250 to 300 FPS (Feet Per Second). By producing that speed, the arrow will get enough kinetic energy to kill any big game animal cleanly and also eliminates the long-range arrow trajectory problem. Weight. Choosing a crossbow based on weight is never easy.

From there, a simple formula reveals the precise energy: Velocity (fps) x Velocity (fps) x Weight (grs.) divided by 450,240 equals Energy (ft.-lbs.). For example, let’s say you shoot 500-grain arrows at 250 fps. Using this formula, 250 x 250 x 500 divided by 450,240 equals 62.47 ft.-lbs.Nov 7, 2019. #9. Those "rules" are from a long time ago. What you need is enough speed to cause the bullet to expand properly and enough energy to push that bullet through to the vitals. You definitely don't need 1200 or deer. 9mm kills deer just fine with 350 ftlbs of energy.All have you to do is square the velocity, multiply by the arrow mass, and divide it all by 450,240. Easy! Here's an example. Let say your bow setup shoots a 400 grain arrow at a respectable 250 fps, the computation of your kinetic energy or "knock down power" will be: KE = (mv ²)/450,240. KE = [ (400) (250²)]/450,240.The driver of a car slams on her brakes to avoid colliding with a deer crossing the highway. What happens to the car's kinetic energy as it comes to rest? Science.
