Can't say, I only use fixed blade broadheads. My taxidermist convinced me to avoid using expandables. She's cut her hands 3 times on a broken expandable blades that were stuck on bone. In her opinion (and she knows what she's talking about) expandables can't be trusted. She's found broken blades so many times she charges extra to work on animals that were killed with them. She's also heard so many stories about lost game and most of them were from guys who were using expandables but rarely from people who were using fixed blade cut on contact broadheads. Expandables may cut a wide wound channel but they penatrate like crap unless you use a very powerfull bow. The more powerfull bow you use the worse you are going to shoot. It's better to use a lighter pound bow (I shoot a #55 Hoyt) and shoot accuratly.
