I bought a tube of these and have been doing some of my own testing. (Not near as extensive as 5 Shots) So far I' m very pleased with the way they fly. I shoot the 125 grain heads and have resharpened them. I don' t think you' ll get them as sharp as an old straight razor, because of the heavy blades along with the angle of the edge, but I' m confident they will cut clear through any critter I come across.
