As an example of one each I killed a mulie at about 150 yds with a 300 WM. 180 Partition started at 3000 fps. Shot behind shoulder, deer did 50 yd death run and had a neat 1" hole thru the deer with little other damage. 35 Whelen similar shot and distance w/250 gr Speer SP started at an honest 2500 fps, the deer took 2 steps and down, completely destroyed the inside of the deer and did not exit. Upon gutting the animal, the guide said he had never seen so much damage to a deer.
