Is there really diference between the fast light arrow and the slow heavy arrow if both are ariving at their target with the same KE? Its .45 acp vs. 9mm. I' m thinking of going lighter and faster than I shoot now.

A faster/lighter arrow will get the target quicker and flatter, but it will also use more energy on impact, therefore slowing down penetration. On deer sized game there is nothing to worry about with most light/fast arrow combo, but some the tougher hide and bigger animals it can result in less penetration and therefore room for error will drop slightly. Now all that being said, I prefer a flatter trajectory, not so concerned about speed. As long as my arrow combo shoots well, the spine is correct & then I match the BH to the critter I am chasing...haven' t any problems to date with this practice.

The problem is the arrows don' t arrive at the target with the same energy. the lighter ones loose speed faster than the heavy ones. Some call it momentum. the heavier the arrow the more energy at the target.

I agree with Bees . . . I am a firm believer in Kinetic Energy. I see it as a mathametical combination of Mass and velocity. If however both of your arrows arive at the target with the same KE the choice would be whichever you want. However, such an equality is highly unlikely.

I am an aluminum user and don' t plan to change. Two weeks ago we shot a new 3-D field course near where we live. What I came away with was an education and a confirmation of this decision. We didn not find one of the 30 target areas that didn' t have numerous broken carbon arrows laying around . . . but there was not one broken aluminum arrow anywhere to be found. I' m not knocking carbons, just stating what we saw.

Way too much emphasis is being put on kinetic energy! JMO
