I shoot my broadheads periodically just to confirm they are still hitting with my field points. Then again, in order for them to impact differently something would have to change in my tuning, and I wouldn’t have to shoot broadheads to know if that happened. With respect to shooting out of a treestand, I guess I’ve never had a problem with it. Our local club has a few elevated platforms, and I’ll sometimes shoot arrows from them as I work through the course. But aside from that, I don’t do anything specific to practice shooting from a treestand.
