Almost my exact same set up except I have a Helix.Hoyt Ventum 33, 70#, 29.5" DL, shooting a 530ish grain arrow with a 2-blade Kudu with bleeders. Arrow hit a little high, middle of the vitals, complete pass through, stuck in ground about 15 yards past the elk. Bull went about 75 yards and piled up.
So yeah, good result but I would have preferred a closer shot. The scenario was absolutely perfect though...no wind, stationary broadside elk, I was shooting from the edge of a meadow that he was in the middle of so I had all the time in the world to range, adjust my slider, get a solid anchor and aim point, and let fly. He didn't react until after the arrow went through him, and neither did any of the cows that he had with him.
I do practice with broadheads out to 80 on a daily basis so I was very confident in my ability to put that arrow where it needed to go.
