I am anxious to try these. Last Bow season I had a doe walk 5 feet from the opening of my blind. Two weeks later I got an eight point on opening day from that blind. The buck was about 25 yards away. The 300 grain XTP I shot completely broke up inside the buck with no exit wound. Had that muzzleloader buck walked within five feet of my blind, I don't know if the XTP would hold up. Clearly I am over-taxing the XTP (which are fine pistol bullets). The new Bloodline bullets should solve that problem.
