To harden bullets.
For such game as the elephant or rhinoceros the hunters harden their bullets with a little tin—not more than one-tenth; if too much is added it makes the bullet brittle, and detracts from its specific gravity; it should be just hard enough to show a slight indentation when bitten. The lead must be first melted as requiring the greater heat, and the tin added afterwards. Type metal, or worn-out type from printing offices, is much used for this purpose; but quicksilver, which, from its own great specific gravity, does not detract from the weight of the bullet, is the best alloy. Sir S. Baker says:—“The lead is melted in a pot, which is kept at red heat. Enough to make three or four bullets is taken in a smaller ladle, and one-tenth of quicksilver added and stirred into it with a bit of iron, as if the quicksilver is exposed to the great heat of the larger pot it will soon evaporate. The rifle bullets used in the army, being compressed instead of cast, are hard enough without alloy; and in breech-loaders, where the bullet has to pass through a barrel which is generally a trifle smaller than the chamber, it would be unsafe to harden it too much.”
Cleft bullets.
The Fingoes and Kafirs cut a small piece off two bullets, so as to produce flat surfaces (Fig. 1); then, while the lead is still clean, press them strongly together, giving them a half turn to expel the air and bring them perfectly in contact. They will adhere so strongly as to bear throwing on the ground, and when fired at a hundred yards will separate only a few inches. A bullet cleft very nearly through with two cuts, so that it spreads into four parts (Fig. 2), makes a fearful wound at close quarters—a conical cut from its base (Fig. 3) particularly so. Sometimes two bullets are connected by a bit of bell wire rolled up spirally as a spring (Fig. 4). We have seen bundles of nails bound together with wire by the rebel Hottentots in imitation of conical bullets. The Kafirs use bits of the legs of iron pots. Some of the native hunters use iron bullets, or rather bolts twice as long as their diameter; but they creep so close that they cannot miss, and follow the wounded animal till he dies, so that they always recover their bullet.
Extemporising bullet moulds.
Bullet moulds may be extemporised in many ways. Two shallow boxes may be made and filled with loam or clay, much as the moulds for cannon shot, before described, are made (of which last no material is better than a pounded anthill), and the surface of the lower one must be smooth. A piece of stiff paper pierced with holes the size of the bullet laid on it, and as many bullets as convenient pressed half way into the clay, the other half must then be pressed down upon it, and when nearly dry the bullets must be taken out, holes made through to the outer surface, on which a small channel should be cut, so that the lead may run to the entrance and not waste itself by spreading. Most likely the mould would be damaged after two or three castings, but it is easy to make a new one. The Dutch boers frequently use blocks of steatite or soapstone, with half the bullet cut into each, and pegs or projections on one half, with corresponding hollows in the other, keep the two parts in true position (Fig. 5).
In Sydney we required a conical bullet mould; and, as such things were not generally kept for sale, we engaged a founder to make a solid block of brass, as in Fig. 6, and in this to bore a cylindro-conical hole, point downwards, about ½ in. deeper than the length of the bullet; another piece was made with a handle at one end, and at the other a projection (Fig. 7), to fit into the block and give the form of the hollow back of the bullet; a hole was bored through this a little smaller above than below, so that when the superfluous lead was cut off the bullet would come away with a tail about 1 in. long, tapering to the end; this was easily cut off with proper pincers; there was a small notch cut up the side of the inserted block so as to allow of the escape of air as the lead was poured in. In some conical moulds the lead is poured in from the side, and in others from the point. We do not approve of either of these methods. The greatest hardness, weight, and density should be at the point, and therefore this should be downward in the mould, while the metal is poured in at the base.
Of course the great range acquired by some of our most perfect rifles with cylinder conical bullets is an immense advantage, for if animals cannot be approached they may be shot at long ranges; and very frequently during the last Kafir war, while parties with the common musket have been defending themselves against savages who occupied almost impregnable positions, those among the colonists who possessed long ranged rifles would occupy a hill perhaps a couple of thousand yards off, and send bullets among the enemy with quite sufficient accuracy to create a very uncomfortable feeling of insecurity.
A very favourite form of gun was a double-barrel, with one barrel rifled, and very carefully sighted for long ranges, and the other plain, and capable of throwing a good charge of buck shot, which we have seen very effectively used at thirty or forty yards.
