Not illustrated. 1901 Excerpt: ...of powder are dependent on the time of ignition for their quickness or the reverse far more than on the rate of combustion. That is to say, they are not as readily ignited by the flash of the cap as black powder is. It has been shown that with some caps the nitro powder lying next the shot wad is not ignited at all, and that these grains of powder have to be ignited by the flame from the first consumed grains of powder. But all the makers of ammunition have been for years improving their caps, so that now there is less difference than formerly between the rates of ignition of various powders. The danger now is that they overdo quick ignition before the powders are made suitable; and there js at least one first-rate concentrated powder on the market in which it is easy, out of a wrong case with a wrong cap, to get pressures in the barrel far exceeding the pressures applied in the proof of the barrel for safety, whereas, in its own proper coned cases, with suitable caps, the pressures are not usually half those of proof. There is a latent danger in relying upon slowness of ignition for slovvth of combustion. It arises from the fact that when powder is burnt slowly there has to be a greater quantity used to get the same velocity from the shot, so that if by chance the whole charge were, by the accident of cap, simultaneously ignited, there would be at once dangerous pressures set up. This very seldom happens, and when it does happen and a barrel is burst, it is at once said that the powder was in fault. In a sense that is true, but the cap was, all the same, the immediate cause of accident. A great quickening up of ignition for nitro powders has been going on for some years now, and this is all in the right direction. Let the powders be made to stand quick ign...
