I killed my a deer with one last season that went all of 20 yards, stopped, then fell over. The entry wound is quite scarey honestly. Complete passthrough.

The XP3's should be even better. They are shorter, use a chisel style tip and have three blades. I can't wait to get a couple packs of these for this season. That is the only knock on the original as PAbowhunter stated. They are prone to bending rather easily. The new heads this year should take care of that problem nicely.
