62 # is plenty of draw weight for a pass thru.

I believe the problem is the sharpness of your broadheads. If I was a betting man, I would say you did not sharpen the Montec's. Right out of the package, Montecs are not near sharp enough to hunt with. The older Montecs ( last years ) are even worse. I bought a package, took the heads out and tried to cut a piece of paper, not one of the heads would cut it. So need less to say, I have had to spend a fair amount of time working up a new edge.
