Though the automatic pistol would be much more accurate at that distance, still I doubt if any one could get more than eight shots on the turkey in twenty shots at three hundred yards.
To be of any use for comparison the actual diameter of the turkey would have to be ascertained.
Judging distance should be constantly practised, under all conditions of light, by judging when out walking how far off a man is, and then walking up to the spot, counting your steps, to see if you have judged right.
Do not measure distance by yard strides and thus draw attention to your movements and raise doubt as to your sanity.
First measure in private, say one hundred yards, and then walk it with your natural length of step when walking at your usual speed, and see how many of your steps go to one hundred yards.
When you know your number of steps for a hundred yards you can measure distances in ordinary walking and without passers-by noticing what you are doing.
My natural walk is 104 steps to the 100 yards at four miles an hour.
Try, when you think you are fairly accurate, to judge the distance a man is off also judge how far a small boy is. You will find at first you think him much further off than he is owing to having got into the habit of judging the distance by the height of the man.
When you come back to judging how far off a man is you will underestimate the distance for the same reason.
Mist makes an object appear much further off than it really is; a sheep close by appears as large as a stag one hundred yards off.
