I have used the 100gr Razor Tricks this past hunting season. These broad heads are razor sharp out of the packet and it did not take long before I had a cut on on of my fingers while taking the broad head off after it was shot into a broad head butt. My arrow as Carbon Express Maxima hunter with total arrow weight 420gr. Bow used was a Bowtech Tribute set at 70# A nice Blue Wildebeest bull gave me a quartering away shot. He went 80 yards before he ran out of fuel.... He left a good blood trail... Entrance wound Again entrance wound Entrance wound into the chest cavity... As you can see these broad heads make a huge wound channel. I shot a double lung shot. Damage on the one lung... Exit wound in the chest cavity Unfortunately I hit the opposite shoulder joint and did not get a pass trough. The broad head destroyed the opposite shoulder. Unfortunately did not get a photo of the shoulder before the butcher got hold of it. :crying: :crying: I am really impressed with these cut on contact 4 blade broad heads and I can recommend them to hunters that need maximum penetration like female hunters or hunters with a short draw length or hunters that hunt with relatively light draw weights.
