The charge of powder must necessarily depend upon its strength. For elephant-shooting, I always rise six drachms of the best powder for the No. 10 rifles, and four drachms as the minimum charge for deer and general shooting; the larger charge is then unnecessary; it both wastes ammunition and alarms the country by the loudness of the report.
There are several minutiae to be attended to in the sports of Ceylon. The caps should always be carried in a shot-charger (one of the common spring-lid chargers) and never be kept loose in the pocket. The heat is so intense that the perspiration soaks through everything, and so injures the caps that the very best will frequently miss fire.
The powder should be dried for a few minutes in the sun before it is put into the flask, and it should be well shaken and stirred to break any lumps that may be in it. One of these, by obstructing the passage in the flask, may cause much trouble in loading quickly, especially when a wounded elephant is regaining his feet. In such a case you must keep your eyes on the animal when loading, and should the passage of the powder-flask be stopped by a lump, you may fancy the gun is loaded when in fact not a grain of powder has entered it.
The patches should be of silk, soaked in a mixture of one part of beeswax and two of fresh hog's lard, free from salt. If they are spread with pure grease, it melts out of them in a hot country, and they become dry. Silk is better than linen as it is not so liable to be cut down by the sharp grooves of the rifle. It is also thinner than linen or calico, and the ball is therefore more easily rammed down.
All balls should be made of pure lead, without any hardening mixture. It was formerly the fashion to use zinc balls, and lead with a mixture of tin, etc., in elephant-shooting. This was not only unnecessary, but the balls, from a loss of weight by admixture with lighter metals, lost force in a proportionate degree. Lead may be a soft metal, but it is much harder than any animal's skull, and if a tallow candle can be shot through a deal board, surely a leaden bullet is hard enough for an elephant's head.
I once tried a very conclusive experiment on the power of balls of various metals propelled by an equal charge of powder.
I had a piece of wrought iron five-eights of an inch thick, and six feet high by two in breadth. I fired at this at one hundred and seventy yards with my two-grooved four-ounce rifle, with a reduced charge of six drachms of powder and a ball of pure lead. It bulged the iron like a piece of putty, and split the centre of the bulged spot into a star, through the crevice of which I could pass a pen-blade.
A ball composed of half zinc and half lead, fired from the same distance, hardly produced a perceptible effect upon the iron target. It just slightly indented it.
I then tried a ball of one-third zinc and two-thirds lead, but there was no perceptible difference in the effect.
I subsequently tried a tin bill, and again a zinc ball, but neither of them produced any other effect than slightly to indent the iron.
