Man, some of you guys on this forum have total **** for luck lol. Maybe whitetails are built stronger than mule deer? 4 years straight using powerbelts and have never wounded a deer or had any powerbelt failures. Every deer shot this year with a powerbelt were pass throughs. Just amazes me when i read all the issues that people have with bullets/guns. Actually i take that back, i found part of a powerbelt in 1 of my deer, the lil green tip from the aerotip powerbelts lol
