I agree with Lawer Daggit, I love the balistics on the 6.5x55, which has no problem with Elk and bear if that is an appertunity. I made up a 257 Roberts Ackley Improved for my son 20 years ago, he has killed deer (115grain Nosler partitioned), and elk (120grain Barnes) with it no problems. If you do not want to handload the standard 257 to get a bit more push, now they have the factory +P loads which are a bit zippier, but still not quite up to the Ackley Imp. Remember, after a hit in the lungs or heart they can only run as far as they can hold their breath!!!
