I have frequently heard persons of great experience dilate with satisfaction upon the good shots made with their little '450 hollow Express exactly behind the shoulder of a tiger or some other animal. I have also heard of their failures, which were to themselves sometimes incomprehensible. A solid Express '577 NEVER fails if the direction is accurate towards a vital part. The position of the animal does not signify; if the hunter has a knowledge of comparative anatomy (which he must have, to be a thoroughly successful shot) he can make positively certain of his game at a short distance, as the solid bullet will crash through muscle, bone, and every opposing obstacle to reach the fatal organ. If the animal be a tiger, lion, bear, or leopard, the bullet should have the power to penetrate, but it should not pass completely through. If it should be a wapiti, or sambur stag, the bullet should also remain within, retained in all cases under the skin upon the side opposite to that of entrance. How is this to be managed by the same rifle burning the same charge of powder with a solid bullet? The penetration must be arranged by varying the material of the bullet. A certain number of cartridges should be loaded with bullets of extreme hardness, intended specially for large thick-skinned animals; other bullets should be composed of softer metal, which would expand upon the resisting muscles but would not pass completely through the skin upon the opposite side. The cartridges would be coloured for distinction. If the metal is pure lead, the bullet '577, with an initial velocity of 1650 feet per second, will assuredly assume the form of a button mushroom immediately upon impact, and it will increase in diameter as it meets with resistance upon its course until, when expended beneath the elastic hide upon the opposite side, it will have become fully spread like a mature mushroom, instead of the button shape that it had assumed on entrance. I prefer pure lead for tigers, lions, sambur deer, wapiti, and such large animals which are not thick-skinned, as the bullet alters its form and nevertheless remains intact, the striking energy being concentrated within the body. The difference in the striking energy of a hollow bullet from that of a solid projectile is enormous, owing to the inequality in weight. The hollow bullet wounds mortally, but it does not always kill neatly. I have seen very many instances where the '500 hollow Express with 5 drams of powder has struck an animal well behind the shoulder, or sometimes through the shoulder, and notwithstanding the fatal wound, the beast has galloped off as though untouched, for at least a hundred yards, before it fell suddenly, and died.
