[QUOTE="Kevin, post: 290677, member: 603"] Don't get hung up on KE. It is not just the KE to be concerned with. It is how the bullet performs at certain velocities. There are tons of examples that can be given here. So I guess I will give one. A .204 ruger shooting 32gr bullets at 4000fps vs a 44mag shooting 240gr bullets at 1450fps, both have just over 1100ft-lbs. Many people carry and trust 44 mags as defense against bears, but I doubt many people would trust a 204. But both have less KE than your setup would have at a 1000 yards. I would trust your combo on elk at 1000 yards maybe a little further. Guessing on some numbers here since I don't know your load, but your bullet is probably going 1800fps ish at 1000 yards which is 1330ft-lbs. One interesting thing to look at is the tests Barnes did. They shot the 168 berger into gelatin at 1890fps. It clearly expanded and penetrated plenty in my opinion. I shoot the 190 JLK and have always figured 1200-1300yards to be a good max depending on temp and altitude. This results in about 1600fps impact velocity. And also corresponds to about as far as my rangefinder will work anyway. [/QUOTE]
