I myself haven’t tried them but a buddy of mine shot them this year. He shot one 1.5 year old buck with one through the heart. The broadhead performed just fine and basically cored the heart, of coarse any head on an arrow will kill a deer pretty fast with a heart shot! He said they flew the same as his field points did, but he did not shoot them past 30 yards. In my opinion 30 yards and past is where you really get to see how an arrow flies.
