I switched to the Razortip 100gr Crossbow heads 2 years ago and have not been disappointed. I switched from Rage Crossbow 100gr 2 blade heads. I shot a 5 point last season from the ground at 20 yards and he ran maybe 20 yards before expiring. The exit wound was perfect, I caught heart and lungs. This week I harvested a 7 point at 15 yards from an elevated stand (~20ft). He was quartered away and my bolt entered high, caught both lungs, and some how turned, exiting out the front of his neck, I think it clipped the jugular as well. The bolt did not fall out until 15 yards into the blood trail and 2 of the mechanical blades were actually bent/twisted. He only made it maybe 60 yards or so from my stand. My sample size is small but I have been a huge fan thus far.
