I have stuck 2 deer with them at 15 yards. First was hit in one lung and heart(quartering away)- it dropped in its tracks. I could not remove the broadhead from the bone. The second was broadside and my arrow passed thru the deer and the broadhead is now completely into the base of the tree that was behind it. This one only went 10 yards. They are fieldpoint accurate for me out to 35 yards.
