I had better results with 3 blade thunderheads but when hunting elk i went to a bigger cut on cantact steef force broadhead but had trouble getting them to fly consistently. My son in law shoots rages and killed a 5x5 elk 2 years ago that left an entry hole as big as his hand. I went to rages last summer and killed a huge doe in the fall. From high shooting down, shot all the way to the fletching from just in front of the tail angling forward down through the body. Even though it didn't exit, there was a good blood trail.
