I shot an elk at a little over 450 this year with the 162 eldx, at that velocity it seemed to work quite well. (Lung shot). I think close quarters at high velocity they still will blow massive holes and lots of meat damage like the old amaxs. Hard to have controlled expansion at high velocity and expect any expansion on lower, longer range velocities with any bullet I feel. Have heard great consistant stories on many animals and also horror stories, but i feel that any bullet out there has two sides.
