[QUOTE="Mysticplayer, post: 56761, member: 8947"] If you held the muzzle of a 1911 in 45ACP loaded with 230gr FMJ ammo against the rib cage of any of these animals and fired, would it cause a lethal wound that would also put the animal down quickly? I hope you said yes. The amount of ft/lbs is around 400 which is pretty small by conventional hunting standards. Energy rated in ft/lbs is not a good indicator of killing power. That debate has raged for decades. What I look for is impact vel vs the expansion characteristics of the bullet used. I want the impact vel to be high enough so that I get reliable bullet expansion of at least 1.25 cal (1.5 is prefered) WITH penetration greater then the distance through the animal's body to reach the vitals. This will create a large enough permanent wound channel to cause a quick death for the game. I use 6.5 cal and larger, with the heaviest for cal bullets for my LR shooting and feel any accurate conventionally built hunting or match bullet will work IF impact vel is high enough to cause that level of expansion/penetration. The ft/lbs generated on my calculator really don't tell the tale. To simplify, bullets like Matchkings, SST, and Ballistic tips should hit going at least 1400fps. Amax and lightly built match bullets might even get down to 1200fps. Heavy large bore cast bullets can drive through large game with impact velocities under 1000fps. Impact energy is again low but do you really want to try and catch a 500gr 45 cal lead slug coming at you at 950fps? We know this has dispatched many a buffalo which are definitely big game. Expansion is zero but the cal is large enough, expansion is not necessary. So ask yourself the question of what game do I want to hunt, at what range? What cal and bullet weight am I planning on using (bigger is definitely better in this game)? What type of bullet am I going to choose? What will the retained velocity be at the furthest range I want to shoot at? How much in game penetration am I likely to get? With that info, you can predict the maximum effective range of your set up for the game involved. Also, will tell you the type of shot you can and cannot take. Now you just have to get out there and practise so that you can actually hit at the range you want and go hunting. Jerry [/QUOTE]
