[QUOTE="Fiftydriver, post: 418865, member: 10"] Foot Pounds of energy is a VERY poor way to determine if a cartridge will be effective at harvesting a deer or not. Let me explain, I have taken literally dozens of whitetail deer out to 300 yards using a 22-250 loaded with Hornady 55 gr SP bullets loaded to 3600 fps. At 300 yards this load has roughly 750 ft/lbs of energy but the rifles I used were exceptionally accurate rifles and even at 300 yards, placing my shot anywhere I wanted was very easy shooting from solid stationary positions as the deer fed out in large fields. Some were neck shots, some were behind the shoulder lung shots, all were one shot kills. I have never lost a deer using that combo but I have also never shot at one over 300 yards. Another point, I have killed alot of deer with handguns, ranging from the 357 Mag up to the 50 Action Express and pretty much everything in between. Many of these had impact energy levels at or under 500 ft/lbs and again, I have yet to loose a deer using a handgun. I do not hunt them at long ranges with conventional revolvers, under 100 yards. Point being, the mount of ft/lbs means very little when it comes to determining if a chambering will be effective on deer size game. What is critical is shot placement, bullet expansion and bullet penetration which needs to be deep enough to pass through the vital zone of the target game being hunted at any angle you decide to take a shot at this game animal. A bullet can have 2000 ft/lbs of energy but if it does not expand it will not transfer much energy to the target game animal and thus will not quickly harvest that animal. That said, if you put a 30 cal FMJ though both lungs of a deer, it will die relatively quickly but it may be able to cover several hundred yards before it does die. Now us a bullet like a 150 gr Ballistic tip and that bullet will expand very easily at 308 Win velocity and transfer more of its energy to the target which will damage more vital tissue if in fact thats where the bullet impacts. Many will say the 308 Win is a 1000 yard rifle. I strongly disagree with that opinion as I have shot this round extensively as well as most of the others in this class building accuracy minded rifles for customers. In fact, the 7mm-08 and 260 Rem will outpreform their larger bore brother at this range. Because of velocity limits and relatively low BC, the 308 just gets caught up in the wind to much to be a true long range hunting weapon. Now in ideal conditions, certainly its consistant to 1000 yards, no question but the retained velocity at that range is such that many big game hunting bullets simply will not expand, again, if there is not reliable expansion, no amount of kenetic energy in the world will help much. Again, its all shot placement and having enough bullet weight to penetrate the vitals and also enough retained velocity to cause reliable bullet expansion as the bullet penetrates the target animal.
