I have shot thunderheads and mussy's for years. I went ahead and tried a three blade rage last year and shot my first buck with it. I took a 40 yard shot and know I hit it perfect. I waited and then went and looked for blood and found what look like someone took a 5 gallon bucket of blood and dumped it all the way to the deer, that was down 60 yards away. Yes maybe that was one occasion and not typical, but I am going to try again this year. For NOW, I am a believer........ I have never in 20 years seen that much blood.... Good luck.....
