I tried all these experiments again at fifty yards' range, with the same advantage in favor of the pure lead; and at this reduced distance a double-barreled No. 16 smoothbore, with a large charge of four drachms of powder and a lead ball, also bulged and split the iron into a star. This gun, with a hard tin ball and the same charge of powder, did not produce any other effect than an almost imperceptible indentation.
if a person wishes to harden a bill for any purpose, it should be done by an admixture of quicksilver to the lead while the latter is in a state of fusion, a few seconds before the ball is cast. The mixture must be then quickly stirred with an iron rod, and formed into the moulds without loss of time, as at this high temperature the quicksilver will evaporate. Quicksilver is heavier than lead, and makes a ball excessively hard; so much so that it would very soon spoil a rifle. Altogether, the hardening of a ball has been shown to be perfectly unnecessary, and the latter receipt would be found very expensive.
If a wonderful effect is required, the steel-tipped conical ball should be used. I once shot through fourteen elm planks, each one inch thick, with a four-ounce steel-tipped cone, with the small charge (for that rifle) of four drachms of powder. The proper charge for that gun is one-fourth the weight of the ball, or one ounce of powder, with which it carries with great nicety and terrific effect, owing to its great weight of metal (twenty-one pounds); but it is a small piece of artillery which tries the shoulder very severely in the recoil.
I have frequently watched a party of soldiers winding along a pass, with their white trousers, red coats, white cross-belts and brass plates, at about four hundred yards, and thought what a raking that rifle would give a body, of troops in such colors for a mark. A ball of that weight with an ounce of powder, would knock down six or eight men in a row. A dozen of such weapons well handled on board a ship would create an astonishing effect; but for most purposes the weight of the ammunition is a serious objection.
There is a great difference of opinion among sportsmen regarding the grooves of a rifle; some prefer the two-groove and belted ball; others give preference to the eight or twelve-groove and smoothbore. There are good arguments on both sides.
There is no doubt that the two-groove is the hardest hitter and the longest ranger; it also has the advantage of not fouling so quickly as the many-grooved. On the other hand, the many-grooved is much easier to load; it hits quite hard enough; and it ranges truly much farther than any person would think of firing at an animal. Therefore, for sporting purposes, the only advantage which the two-groove possesses is the keeping clean, while the many-groove claims the advantage of quick loading.
The latter is by far the more important recommendation, especially as the many-groove can be loaded without the assistance of the eye, as the ball, being smooth and round, can only follow the right road down the barrel. The two-grooved rifle, when new, is particularly difficult to load, as the ball must be tight to avoid windage, and it requires some nicety in fitting and pressing the belt of the ball into the groove, in such a manner that it shall start straight upon the pressure of the loading-rod. If it gives a slight heel to one side at the commencement, it is certain to stick in its course, and it then occupies much time and trouble in being rammed home. Neither will it shoot with accuracy, as, from the amount of ramming to get the ball to its place, it has become so misshapen that it is a mere lump of lead, and no longer a rifle-ball. My double-barreled No. 10 rifles are two-grooved, and an infinity of trouble they gave me for the first two years. Many a time I have been giving my whole weight to the loading rod, with a ball stuck half-way down the barrel, while wounded elephants lay struggling upon the ground, expected every moment to rise. From constant use and repeated cleaning they have now become so perfect that they load with the greatest ease; but guns of their age are not fair samples of their class, and for rifles in general for sporting purposes I should give a decided preference to the many-groove. I have had a long two-ounce rifle of the latter class, which I have shot with for many years, and it certainly is not so hard a hitter as the two-grooved No. 10's; but it hits uncommonly hard, too; and if I do not bag with it, it is always my fault, and no blame can be attached to the rifle.
For heavy game-shooting, I do not think there can be a much fairer standard for the charge of powder than one-fifth the weight of the ball for all bores. Some persons do not use so much as this; but I am always an advocate for strong guns and plenty of powder.
A heavy charge will reach the brain of an elephant, no matter in what position he may stand, provided a proper angle is taken for attaining it. A trifling amount of powder is sufficient, if the elephant offers a front shot, or the temple at right angles, or the ear shot; but if a man pretend to a knowledge of elephant-shooting, he should think of nothing but the brain, and his knowledge of the anatomy of the elephant's head should be such that he can direct a straight line to this mark from any position. He then requires a rifle of such power that the ball will crash through every obstacle along the course directed. To effect this he must not be stingy of the powder.
I have frequently killed elephants by curious shots with the rifles in this manner; but I once killed a bull elephant by one shot in the upper jaw, which will at once exemplify the advantage of a powerful rifle in taking the angle for the brain.
