Not by me.
When you screw up and wound a leopard, your PWH will likely track it with a shotgun, but a tiger is a LOT bigger animal.
There is a lot of big game poached by underpaid Slobbovian troops who just hose the animals with automatic rifles, but it is not something one would do on purpose. I guess if you are faced with a loose "pet" tiger or lion, you will do the best you can with what you have, q.v. Ray Ordorica vs a bear with 9mm.
The typical Howdah Pistol maxed out at .577. Hamilton Bowen built a modern version of the rare .577 revolver on a Ruger action. It got a 400 gr bullet to 725 fps on black powder, so it would really have been a last ditch defense, these days you would be better off with something like a .475 Linebaugh.
T. Roosevelt thought a .405 Winchester was a suitable lion rifle.
