I would try it on urself before you head out into the bush looking for a tiger,make sure you get good skull penetration at close range.On a serious note i knew an old lion hunter here in MT that killed cats for the F&G back in the good ole days,he packed a lever action .22 mag and swore by it for treed lions,I would guess he killed several hundred with it over 40 years of being a govt trapper so its not entirely impossible,tigers probably have double or triple the bone mas of a mtlions skull so it would take an ignorant jackass to even consider it,i vote for ignorant.
As I sit and glass, which is common for hunters out west, I have sort of quickly discovered something I never learned when I was younger.
In my youth I had enthusiasm and spirit. In my middle to advancing years I have creaky knees, arthritis, and I tire more easily than I used to. Where I used to sit on the cold hard ground I now look for that soft spot to sooth my tired muscles. That leads me to my tip.
Carry your soft spot with you!
In my pack I carry an air filled, ultralight, camping pad....
