Ammon B. Critchfield, A report on the feasibility and advisability of some policy to inaugurate a system of rifle…
“ The shooter cocks the rifle and aims at a target a foot high on the other side of the room, and when his aim is satisfactory, pulls the trigger. When this is done an electrical connection is made which shoots forward the rod which is on the standard, so that its point punches a hole in a miniature target like a visiting card, which is placed in front of it, which hole is mathematically on the same relative place on the card target as would have been made in the target at which the shooter was aiming if he had a bullet in his rifle. ”
