Class 1 comprised twelve bore double guns, not exceeding 7-1/2 lbs. in weight; the charge for the breech-loaders was three drachms of powder, and one ounce and a quarter of shot; that for the muzzle-loaders, two and three-quarter drachms of powder, and an ounce and a quarter of shot. The question will be asked why were both not charged alike? and the answer is, because the advocates for breech-loaders well knew the loss of power caused by the enlarged breech end would require a larger quantity of powder; yet, with this advantage, the result was a verdict in favour of the muzzle-loaders of nearly two to one. I quote from the _Field_. The aggregate number of pellets in the targets from breech-loaders was 170, the penetration 19. The aggregate number of pellets put in by the muzzle-loaders was 231, the penetration 48; and this was effected with a quarter of a drachm of powder less. Few will doubt that this must be the inevitable result. Force cannot be expended and retained: we “cannot eat our cake and have it.” If force is destroyed by friction, it is as useless as if it had never been generated. So much, then, for the shooting qualities of the breech-loader. And now comes the question, of much more importance than the shooting qualities of these guns: namely, can all this force--30 per cent., in fact, of the whole charge--be thrown away with no worse result than the mere wasting of the powder? Is there no change taking place in the barrel of the gun every time it is discharged? Iron and its combinations are as certainly limited in their duration as is human life itself. Every bar of iron is capable only of resisting a certain amount of pressure; every successive strain on its fibres deteriorating it more rapidly; and whether it be the mainspring of the lock, or a gun-barrel itself, a certain number of strains will destroy it. This being the case, how much more rapidly must a breech-loader be destroyed where 30 per cent. of the charge is always “absorbed” on the sides of the barrel in the cavity alone. This a lengthened experiment will prove; though the fact is so self-evident, that no experiment is required to demonstrate it. Caution in gunnery is absolutely necessary under the most favourable circumstances, and disregard of perfection in the construction of a gun is quite unpardonable; then what shall be said of that member of society who, with all those facts before him, can say to his customers, “I advise you to have a breech-loader: they are really good guns?” In what estimation such a tradesman must be held I will not venture to say. Much more might fairly be said against these guns, but I sum up the whole in the following damnatory sentence: Breech-loaders do not shoot nearly so well, and are not half so safe, as muzzle-loading guns.
