I don't know about the Magnus, but my 1-3/8" Zwickey Delta two blades blew through a whitetail buck so fast I couldn't believe it...at 22 yards...from my 46# Kanati drawn to 28".
The buck only went about 85-90 yards. I could see him from where the arrow landed, but the blood trail would have been a bugger to follow if I would have needed to. I got both lungs, but most of the bleeding was internal.
I have also killed deer with 125 grain Snuffers and Woodsman broadheads. These gave awesome blood trails, but penetration was not as good with the Woodsman, partly due to the angle of the shot and hitting ribs going in and out.
I'm still not 100 percent sure of the Deltas in terms of blood trail, but there is no question about penetration. They are also very easy to get scary sharp.
