Rick, I took my bull elk with a Muzzy tipped Beman Trophy Hunter 70/90 back then out of a 70lb Hoyt Tenacity...my arrow passed through and went another 15 yards and buried in the ground. I watched the guy I went with knock a bull of it's feet with a Muzzy at 10 yards...I don't think you'll have a problem with Muzzy's...remember, big animal, shot placement...dead animal.

ps, my bull went about 60 yards and I watched him go down, the blood trail looked like a Tractor/trailer lost a hydraulic hose...have a great hunt.
