A brief story and a question for you all.
I shot a buck 6 or 8pt not sure. Anyway, grizzly two blade single bevel, shaving sharp plus. Broadside, shot looked good arrow went straight through and stuck 6" in the dirt. Arrow was covered in broken bubble blood end to end. No bad smell. I looked for 3 hours and never found a single spec of blood or a body.
My brother in law shoots the same type of head only a single bevel Zwickey. He had the same experience twice. I went heavier, 620 grain arrow, and two blade in case of hitting bone. My old NAP spitfire three blade 1.5" mechanicals always left a great blood trail. My old arrow was only 420gr.
So my question is, have any of you had this experience with two blade heads? If you have shot two blades and also shot three blades or two with a bleeder. What has given you the best blood trails and reliability in case the shot is not all you hoped for or the animal moves? Thanks for your help. It's great to have the wisdom and experience of many.
