In order to arrive at striking velocity from these trials, it was necessary to compare the time taken at one range with that taken at another range by a different cartridge.

That in some cases the leading pellets are recorded as slower than those behind them, is not, as would at first sight appear, an absolute disproof of accuracy, because it may be that the leading pellets are constantly dropping back, and others are becoming leaders. Obviously the fastest pellets lose speed at the greatest rate, and obviously, also, the leading pellets get least help and give most to their neighbours, by setting up air disturbance, or a breeze, in the direction of the load.

We all know from paper pad and strawboard tests that the penetration of pellets from the same discharge often varies as two to one. Some of these records do not confirm this; but as they can only be accurate on the assumption of that which must be true—the fluctuation of relative positions of the pellets in flight—this adds to their value, because that assumption is also required to explain the greater known variation in penetration than the most indicated in these tables of speed.
