Whitetails from a tree, 3-6. Elk on the ground,12-18. Black bear, 6. Caribou, as many as I can fit in the quiver.
Just because there are many more opportunities at one particular hunt compared to another. Caribou, LOTS of practice shooting to help judge distance and I'll lose a few. Plus shots at ptarmigan,. etc.
Treestand hunts, I know my yardage and dont need to take more than one practice shot from a stand, if any. I've had bears smell a practice arrow sticking in the ground and bolt!
Same with elk, practice shots! Lots!
