Here are a few examples with the 42 grain charge: allowing 6 inches for half the length of the bird, and adding this to the diameter of flying shot column at various ranges, it is found that in order to get clear while the shot column is passing, the bird at 60 feet per second takes .041 of a second. At 100 feet rate of flight he will take .025 of a second, and the shot takes but .022, so that the game does not get an advantage here at 30 yards. But at 40 yards the slow bird takes .05 of a second and gets no advantage; the fast one takes .03 of a second, and here the time of the column is .036, so that, however good the timing, the bird misses some shot. At 50 yards it is still worse for the slow bird, which takes .062 of a second to get through, and better for the fast one, that takes only .037 of a second, when the shot occupies .046 of a second for the whole column to pass.

There is not much difference for the 49 grain charge from the choke bore. At 30 yards the shot column takes .027 of a second to reach the distance after the first pellets are up. The 60 feet a second bird takes .041 of a second, and the 100 feet per second bird takes but .025, or a less period than the shot column. At 40 yards the slow bird takes .050 and the fast one .030 of a second, and the shot occupies .042 of a second. At 50 yards the times are .062 for the slow bird and .037 for the fast one, and the period taken by the shot column is .050 of the unit of time; so that at the longer range the best timing possible would only give the game 37
