I‘ve killed the first two of my three man eating Royal Bengal tigers with a shotgun (a Pakistani single barrel 12 gauge Sikender with a fully choked barrel) in 1981 and 1988. I was using Eley Alphamax L.G shells. Both tigers were shot only once. Here is the photo of the second tiger. I have the photo of the first one in my album and will eventually take a photo of that one too.

Let me be very very frank: UNDER NO CIRCUMSTANCES IS ANYBODY TO TRY TO GO AFTER A TIGER OR EVEN A LEOPARD WITH BUCKSHOT. I did it because I was stupid enough to listen to a fibbing forest guard who worked for me at the time (who claimed to have killed several Royal Bengal tigers with L.G buckshot) and I believed him. The first one nearly killed me.
I detailed the incidents in my book. But in short order, here is the basic gist of it:
Man Eater #1: I’m inside a security guard’s hut in a fish farm. With me is one forest guard, holding a six cell torchlight. Tiger killed and partially fed on a bullock and we know that he will come back to his natural kill (to resume feeding). Tiger comes at 8:30 PM (give or take), forest guard turns on torchlight. I see the two glowing eyes and fire. Range can’t be more than 20 yards. Tiger takes the hit and gets out of our line of sight. We can’t see the striped bastard but we can hear him growling. At around 9, rain starts. We get scared, because we can’t hear him now. In the morning, my other officers come. We find a blood trail and eventually find the animal dead. Based on how far he had gone and his rate of decomposition, a postmortem suggested that he succumbed to the gunshot wound SEVEN FULL HOURS after I shot him. All eight L.G pellets had hit the tiger. Six in the base of the chest … ALL of which flattened out like clay putty without managing to reach the heart. Two tore into the throat. And that was what eventually did him in. He measured 9 feet 9 inches.
Man Eater # 2: I’m on a macchan in a cattle farm. With me is a forest guard, holding a six cell torchlight. Tiger killed and partially fed on a bullock. So we’re waiting for him to return to his natural kill. Tiger comes at 10PM (give or take), forest guard turns on torchlight. I see the two glowing eyes and fire. Range can’t be more than 22-25 yards. Tiger takes the hit and disappears. In the morning, my officers come and we do a search. We find him after spooring blood trail. Dead. Based on what the postmortem suggested, he succumbed to the gunshot wound no less than FOUR HOURS after I shot him. 7 L.G pellets had hit the tiger in the base of the frontal chest area. MOST of them had flattened out on the rock hard muscle under the skin. ONE had managed to make it a little deeper. But still didn’t reach the heart, properly. The tiger died from blood loss. He measured 9 feet 7 inches. I got myself a proper rifle after that incident (my Churchill Gunmakers Model Deluxe 7x57mm Mauser). I used it to kill the final man eater in 1989. Male tigers in this region average 310 pounds. So lighter (but faster and more aggressive) than the Royal Bengal tigers found in India and Nepal’s Terrai region.
On the subject of African leopard, I’ve personally seen Remington 3“ Magnum OOO Buck fail to penetrate the skull and shoulder muscles of a large male at four meters. The pattern was tight enough to be covered by my palm. An African white hunter who guided me told me a story of how he once shot a charging female leopard in the head with a Remington 11-87 that was loaded with South African Swartklip L.G shells (which hold eight pellets). Leopard kept going and was fortunately floored with a 300Gr Nosler Partition fired from a .375 Holland & Holland Magnum (a pre ‘64 Winchester Model 70). A postmortem revealed that none of the L.G pellets had managed to get through the skull bone (though the skull bone did get cracked and dented). Range was so close that even the plastic wad was found lodged in the leopard’s skin.
I’ve personally killed one male leopard with Federal 3” Magnum copper plated OOO Buck (during a charge when we followed him up after he got wounded). Shotgun was my white hunter’s Valmet Model 412 O/U. The first shot took failed to stop him at 10 meters. Second barrel stopped him at four meters. Postmortem revealed that even ”Premium” copper plated OOO Buck pellets would flatten upon hitting leopard skull. We found a grand total of 12 pellets in him from the two shots (a Federal Premium 3” Magnum OOO Buck shell holds ten, so it’s anybody’s guess how many pellets were from the first shot and how many pellets were from the second shot). The ones from the second shot tore through his heart.
My conclusion is that unplated buckshot (regardless of size) will not work on big cats (unless it’s a fluke, which is what happened to me). Copper plated OOO buckshot won’t be effective at ten meters, but MAY be effective under five (for leopard, that is).
Be smart. When going after a wounded leopard, use:
Option 1: A fast handling double rifle in either 9.3x74mm R or .375 Holland & Holland Magnum or .450/400 Nitro Express or .500/416 Nitro Express (using fast expanding bullets like Nosler Partitions)
or
Option 2: A shotgun loaded with 3” Brenneke Black Magic slugs
