[QUOTE="JASmith, post: 1586479, member: 24844"] Apologies for not commenting sooner! I just saw the thread and it addresses one of my favorite topics! Short answer to the OP "Does Energy = Lethality?" A big NO! That applies to medium and large game. The primary lethality influence in lethality is hitting the desired impact point on the animal. Muzzle velocity, ballistic coefficient and shooter skills are the key parameters in getting the hit. Next most important is expansion and penetration. One should ask "Will the bullet likely penetrate deeply enough to get into the vital regions? Second, will it expand enough to cause rapid loss of blood pressure in the brain so the animal drops quickly?" The most important factor in hunting bullets impacting [I]within their design velocity[/I] is bullet weight. For example, A 100 gr classic lead core expanding bullet or a 60 grain lead free hunting bullet should work well for southern whitetail weighing 125 lb. On the other hand, should one be after 500 -700 lb elk, classic bullets weighing between 160 and 200 gr or lead free hunting bullets weighing 100 and 125 grains should give a good balance between recoil and terminal performance.
