Well, I have shot a number of deer and boar with that particular bullet, usually around 2,000 FPS and it has done an excellant job for me so I wont think twice about using it again. Of course I have never shot one between the lungs or when the Adrenalin was up, but most have been bang flops shot through both lungs and just above the heart [my favorite spot]. I think conditions and shot placement make a big differance with all bullets. Lee
