If forced to forced to face up to financial reality—meaning I have to grab a rifle from my own gun safe—I'm pulling out my Ruger Magnum in .416 Rigby. The speed of the tiger's charge means I'm only getting off one shot, but that uncomfortable fact is offset somewhat by the confidence I have in the Ruger. I've hunted with it in three countries in Africa and have shot it out to 300 yards. It's accurate and the cartridge has been sending animals to their reward with aplomb since it was introduced back in 1911. You could do worse.
