With this I contrast my bullet of 1841, at page 354, and a very slight inspection will be sufficient to satisfy any one of its superiority: every practical rifle-shooter knows that the smoother all the surfaces of the bullet, the more extensive and accurate is the range. That the French experiments should have given unsatisfactory results I am not at all surprised: the flat surface on the point of the bullet must offer a large space for the resistance of the atmosphere, during 1,000 yards of flight. Then to this must be added the effect produced by the rings around the bullet; and when the resistance of the atmosphere and that produced by the friction of the bullet are added together, we need not be surprised that the results of the experiments turned out very unsatisfactory. Surely, if the French school invented the bullet which produced this wonderful revolution in gunnery, they would have rendered it perfect, instead of producing it in a more rude state in 1848 than I had produced it in 1840.
Another point affording strong evidence that the whole was copied from my work of 1842, is this. In my original plan the bottom of the cavity of the bullet was flat, exactly as it now appears in Captain Minié’s annular ringed bullet. In 1843 this was changed into a hemispherical bottom; and this exists in all English expansive bullets, as the adjoining woodcut will show.
In 1852 I produced a new form of cup, intended to obviate the use of the heavier substance, or conical piece of iron. In addition to a cup of a parabolic spindle shape, it had a rim like that on a man’s hat, as the woodcut will show.
A great advantage is gained by this contrivance in effectually expanding the bullet, and thus closing up stray appendages, which are found to exert considerable influence on the ultimate direction of the bullet. A slight tail of cartridge-paper, a string, or an appendage of any description, exerts such an important influence on the bullet’s flight, as to cause it in some instances to describe a curve, the termination of which is very eccentric, and commences from the very base of its starting. It is evident, then, that great accuracy is necessary in order to produce a perfect expansive bullet. English bullets are pressed into shape by machinery, whilst in France they are formed in the ordinary mould; this, however, is at all times an uncertain mode of making them: a slight cavity in the head of the bullet would make it eccentric in its flight; and this is very difficult to avoid: a slight puncture, or an eruption on the surface, would, during a lengthened flight, be materially acted upon by the atmosphere, so as to influence in a great degree the direction of its flight.
