I recently shot a nice buck with the Tac15. See LRH Deer hunting. I shoot Rocket Steelhead XL 100gr mechanical broadheads. As you know, the Tac15 generates some serious KE, about 150 ft-lb, and this appears to have saved my bacon. Below is the picture of the shoulder blade from the deer - I butchered it last night. I messed up on range estimation (thinking the deer was at 40+ yards vs. 35 yards) and shot this deer about 3 inches high, and also a little too far forward. The arrow punched straight through the shoulder blade, exited the far side of the deer and stuck in the ground so hard that it was a bear to pull out. I was saved by the tremendous KE of this monster bow. Thanks PSE! This also says something about the durability of the Steelhead XL - all three broadhead blades made it through the shoulder blade of the deer. Thanks Rocket!
