Getting ready for a lion hunt in Africa and am planning to take my Winchester mod 70 in .458 win mag. Any suggestions on a good bullet.? I hand load and have looked at a couple of bullets, but do not have any experience with lion hunting and understand that you do not need a real tough bullet, but one that will open quickly and still get through muscle and bone in case of a charge. Any been there got that check in the box experience? Thanks for the input.
