Kansaswiderack is right. Any setup for whitetail is adequate for black bears and your Muzzy will be more than proficient. A black bears hide is actually thinner than that of a whitetail although the hairs can be thicker. Like he said, avoid the shoulder bone and make a good placement and your setup will be fine. I took my 98 Quebec black bear with a 3 blade 100 gr Muzzy on the tip of a Beman ICS340 arrow out of a Hoyt Tenacity II....the shot passed the length of the bear and shattered on a rock behind him. We recovered him a mere 50 yards from the shot.
