I guess I could shoot my double rifles in one of those contraptions that hold the rifle and are bolted to the bench.... But what good would that info do me???
What I need to know is, can I,with this rifle and load,hit that animal, from a shooting position I can assume at this location?
In other words when the PH says "Can you hit him from here?"
I need to know how to answer. Shooting off a bench does not get me there.
I test and zero my rifles from the position I will shoot at that distance.
Give it a try, with a little practice you might like it.
