I'm not sure if the four blades will make a difference or not. I shot a dall sheep several years ago with a four blade muzzy. I was certain I had missed, the sheep didn't run, just walked about 50 yards and then fell over dead. You would think you could see blood on a white animal with binos, but nothing! I've shot deer with Zwicky eskimo's and deltas with zero blood until the dead animal. I have had great blood trails with two blade single bevels, both grizzlies and cutthroats.
