The more elaborate ones have a bell attachment which strikes after any desired number of beats of the pendulum. If you want to practise three minutes’ exposure of target, you set the metronome at half-second beats (120 to the minute) and the ball to strike at every sixth beat.
Accuracy of course depends for what purpose you are practising, but to be able to hit an object a foot in diameter, at ten yards’ distance instantly, is ample for self-defence.
CHAPTER XX
SNAP SHOOTING
When you have become fairly proficient at hitting moving objects, you will be able, with a little practice, to soon pick up the knack of snap shooting.
By snap shooting I do not mean the sort of competition where you are given three-seconds intervals. That is merely “fast deliberate aim,” in fact is as slow as allowable for practical shooting, slower is mere target shooting.
Snap shooting is when the pistol is fired the instant it is levelled without any dwelling on the aim.
Use a big target, at ten or twelve yards.
