I also have taken 3 large deer with these. MZ was 2365fps.
#1 @ 35yds(2200fps impact)-downward in between shoulders at base of neck, bullet lodged in spine mangled >1" expansion after traveling 6" through bone..DRT(obviously).
#2 @ 220yds(1500fps impact) behind shoulder .5" in & 1" exit...He staggered, fell over and slid down the snow covered hill he was on.
#3 @175yds (1750fps impact) also behind shoulder .5 in & 1" exit...Buckled on the shot and didn't get up.
They perform well at these speeds, but any slower than 1500fps impact I would choose the 200 gr .40 XTP...It is also a spectacular killer that is every bit as accurate in ALL of my .45's.. It's only limitation is that it will fragment badly above 2100fps impact velocity, however I've intentionally driven this bullet @2635fps into a buck at 50yds into his brisket after being warned it would be a bad choice...Well that's the fastest I've ever seen a deer die from a non spine/CNS hit. Deer hit the ground before I heard the shot I think. The bullet entered into chest head on and exploded inside never penetrating diaphragm. Chest cavity was like a blender drink. Largest piece of bullet I could find was several fragments of the jacket no bigger than a BB. This was clearly an example of hydrostatic shock. I'm confident that at slower impact speeds(aka long distance or low recoil loads) this would be a better killing bullet than the SST.
