With good shot placement, it will kill them. You don't want to take anything but a brain shot. Not knowing your age, hunting experience, or how you plan to hunt them, I'm not telling you to go for it. It can be done reliably, it's not for everyone though!!

I might suggest a hp besides the stinger, I like stingers and shoot them most of the time, I think they may prove a little explosive for this. ie ( not enough penetration)
