I shot a doe last night with a slick trick at 10 yards. The shot was at an extreme upward angle so I only hit one lung but got a passthrough. The deer ran about 15 yards and stopped. She looked like she had been untouched so I knocked another arrow, drew back, and took the only available shot I had. Right in the head. Now before you start going into ethics and all that let me explain that this was my first deer with a bow and she was not going to get away. The second shot was only 8 yards from the base of my tree and also was a passthru. On a side note: A hard deer skull will take your sharp slicktrick blades and turn them into very dull serrated blades.
