Apparently it is mistaken to place the actions of shooting in this or any other sequence of events. It is said, “You see the game, you aim, your eyes tell the brain your aim is true, your brain orders the muscles to let off the gun.” That is possibly correct for some people, but the author does not believe that any fast crossing game would ever be killed if it were so. His view is that there is the game; your brain now instructs two sets of muscles to move in different directions, one to move the gun and another to pull the trigger, and at the same time informs each how rapidly to act in order that lefthand gun-swing and right index-finger pressure may arrive precisely together. This is what is called hand and eye working together, but it should be hand and finger. The eye certainly may observe whether the two things have been done at the same instant of time, but when they have not there is no time for correction; all the eye can do is to inform the brain that the swing did not catch up before the gun was off, or the reverse, so that the brain may correct the missed timing for the next shot. It is necessary to observe that the finger pressure starts, as does the swing of the gun, before aim is completed, and that if the latter were got before the order to pull were given by the brain, it would be lost by the mere continued swing of the gun before the order could be executed.
What has to be considered, then, is what appears to the brain at the instant of discharge. The quicker the perception of things as they happen, the more space will be observed between the muzzle and the crossing bird as the gun races past the game. The slow perception will not observe that the gun has passed the bird when the explosion occurs, and this clearly accounts for some good shots declaring they never make any allowance for crossing game, but shoot “pretty much at ’em.” Of course they do nothing of the sort; but they tell you what they perceive. They do not observe that in the interval between pulling trigger and the shot leaving the barrel the gun has travelled past the game very considerably, and what they have observed is the relative position of gun and game at the time the trigger gave way. For their class of shooting, therefore, they must look for less daylight between gun and game than the person of quick perception, who sees most of what there is to observe.
The velocity of light is so much greater than the velocity of recoil, that it may be questioned, on that ground, whether this is the right explanation, on the assumption that only recoil would stop the perception of the relative positions of game and gun. But were it so, it is necessary to remember that the velocity of light has no relationship to the velocity of brain perception through the eyes.
But probably recoil has nothing to do with the matter for the man of slow perception, and to him the discharge is done with as soon as the trigger gives way. It appears, then, that the slower brain perception is through the eyes, the less observed allowance a swinging gun will require.
Is it possible to shoot fast crossing game without a swinging gun? For an answer to this, the author has tried to come back from the first shot to meet flying game behind with the second barrel, but has found it impossible to kill. Here the swing is in the opposite direction to the movement of the game, and it invariably carries the shot behind the game. Assuming it to be possible (as it is) to throw up the gun to a point of aim at which game and shot will intercept each other, the gun is mostly, possibly always, given a swing in the direction of the game’s movement by the mere act of presenting. That is to say, the shooter is raising his gun from a position more or less in the direction of the game when he starts the movement, and as the game is not there when the explosion occurs it is obvious that the gun has done some swinging, possibly unknown to the shooter.
Much reliance upon this kind of racing with the game has its disadvantages as well as its advantages. It reduces the necessity for accurate judgment of speed of game to a minimum. That is to say, if the gun races the game, and gets ahead of it unobserved by the shooter, the pace of the gun is set by the pace of the game, and the unobserved allowance ahead is also, and consequently, automatically adjusted by the game itself—that is, by its angle and its speed.
But this method of shooting takes no account of the height of the game, and possibly this is one reason why high pheasants are so very difficult to many excellent marksmen at lower birds.
The pace of game high and low being the same, it is, relatively to the movement of the gun, slower according as distance increases. If the gun muzzle has to move 5 feet a second to get ahead of game crossing at 20 yards away, it need move but 2½ feet per second to get ahead of game 40 yards away and moving at the same velocity. Consequently, when the whole allowance is given unconsciously by swing, and is just enough at 20 yards, it is clear that the same swing will only give the same unconscious allowance at 40 yards, and that this will not be half enough at that range, where the pellets are travelling slower and have double the distance to go.
TAKING A STEP BACK WITH THE LEFT FOOT AS THE SHOT IS FIRED SAVES THE BALANCE WHEN THE GAME HAS PASSED FAR OVER HEAD BEFORE BEING SHOT AT
