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.
There can be too much of a good thing with antler rattling.
I like to hit the horns together for a good 30- to 40-second rattling sequence and then hang them up and resist the urge to hit them again.
This works to the hunter's advantage, because if a buck has heard it, he may have been 300 or 400 yards away and he comes in and he's not exactly sure where it came from.
When finally is time to rattle again throw a slight change-up into the routine.
The second time, don't rattle as loud...
