[QUOTE="entoptics, post: 1788540, member: 104268"] I disagree. I talk about energy in projectiles all the time, and I certainly have a pretty extensive education in science... More relevantly, MANY accomplished hunters do the same. Why? Because it is a good metric of 2 quantities required for creating wounds. Mass and velocity. In other words, it can summarize two variables in a relatively easy to compare number. For example... Generic "Hunting Ammo" A and B are both "expanding boat tail bullets", and both have about the same ballistic coefficient (or the drop printed on the box is roughly the same). Ammo A has 2000 ftlbs of energy at 350 yds and B has 1000 ftlbs at 350 yds. It's immediately obvious to me (and most reasonably educated hunters), that Ammo A is likely heavier (bigger) and suitable for elk and ammo B is likely smaller (lighter), and suitable for deer, and perhaps marginal for elk. How do I know? Well, I know many folks have killed deer with a 243 Win (similar energy to B), but most anecdotes would indicate 243 is marginal for elk. Many people choose 30-06 or 7mm Mag for elk (similar to ammo A) and report great success. In summary, I believe energy is a great synopsis of performance, when considered in tandem with bullet design. Sure it can be misleading, when comparing two radically different bullets like a 110 V-Max in a 300 WM vs a 130 Accubond in a 6.5 CM, but only the most uninformed would make that comparison. [/QUOTE]
