I cant say how well they work on other animals, but I went on a russian boar hunt this past weekend, and one of the guys with me was trying out the rage 2 blade. His first shot was at 17 yds, and it only penetrated about 5 inches. That hog was still running around 2 days later when we left. The hog he ended up getting he put three arrows in the guide put a 357shell in it, and never got an exit wound. The other guy with me got a near pass through at 40 yds with the G5 tekken 2 mechanicals. It still took one more arrow and a 357to finish it off. I used GrimReaper razorcut 100grain and got a near pass through at 30yds, but my arrow shattered. It still took a second arrow as well to end it, but at least not a bullet. I can say, that even though the Rage didnt penetrate well, it had a MUCHlarger entrance hole. I have no doubt they would tear up a softer hided animal like a deer.
