I shot them for 5 years and took 5 deer with them. On only one of those did I get a pass-thru though. That was the main reason I stopped using them. At first I thought it was shot placement but then I shot a doe broadside at about 20 yds perfectly and still didn't get the pass-thru. I'm unsure why but I kinda got spooked after that and started using Muzzys and Slick-Tricks. I think they are one of the better expandables but I would have felt better shooting all the way through the animal.
