I think it is well to begin to shoot at moving objects at first, instead of rapid shooting. You can begin at slowly moving objects, which does not hurry and flustrate you as shooting against time may do.
Above all do not attempt to shoot as many people tell you to.
The greatest bar to shooting at moving objects with the rifle or pistol is the way most men shoot at them.
What they do is to aim at a spot and shoot when the object arrives there. Shotgun men do not make this mistake, but men used only to lying on their faces like a squashed frog in rifle shooting invariably do.
Wherever you go to a rifle meeting where there is a competition at a moving target, “Running Deer,” “Running Man” or “Gliding Man,” etc., it is always the same.
A few men shoot as they ought to, and win all the prizes. The bulk of the competitors lie on their faces, as they were taught to do at stationary targets, take a deliberate aim at a spot on the background, and wait till the target gets opposite their aim.
Then—boom—the dust flies up where the target was a moment before, but it is now—elsewhere.
It is as if you tried to catch a fly by putting a finger on him when he is on the table-cloth. You will put it where he was, not where he is.
The correct principle (the one with which I won the Rifle Running-Deer World’s Championship at the Olympic Games in 1908) is to treat the rifle or pistol exactly as if it were a shotgun.
Assuming you are not familiar with shotgun shooting, get a man who is a good shot with the shotgun to coach you, when practising with the pistol at moving objects.
