Besides these objections to this target, another and more serious one
is the irregularity in the manner of breaking the circuit. It has been
proved that times required for a flat headed and an ogival headed
projectile to rupture the current are very different.
To remedy these defects a new and very ingenious target has been
devised and used with great success at the United States Military
Academy at West Point. The top of the target is a wooden strip, F, on
the upper side of which are screwed strips of copper, A A, about 1/2
in.
