I was lucky enough to spend a couple of days in a blind last week. The dark moon phase in August is always a good time in the hide. I tested the 125gr Viper Tricks from Slick Trick. They were on my Carbon Express Maxima 350 arrows for a total arrow weight of 450gr. My 2010 Bowtech 350 Destroyer at 70# shoots the arrows at 308fps... Early Wednesday morning in the blind and I finally got the Gemsbuck bull I have been looking for... After dropping him at the skinning shed I jumped into another hide for looking for an impala ram but when after a couple of hours this boy presented the shot I could not resist. The Gemsbuck was 36 and the Kudu 53 1/8 The Viper Tricks performed perfect with straight line penetration busting ribs on entry and exit on both animals.
