Elephant poachers hunt elephants with AK47s.
They just drive up next to an elephant with nice tusks and a bunch of guys with full auto AK47s put about 30 rounds each into it. Elephants are made of flesh just like humans. Poke enough holes into a body and the internal organs will leak blood(among other things) out and then various body systems start to shut down... eventually if enough blood loss, the brain shuts down as well. The more holes, the quicker the process.
If you are trying to make a humane kill...well, that’s a whole nuther story.
And then there is this funny thing we westerners refer to as “sportsmanship”. For some reason, sportsmanship encourages us to use guns with very limited ammo capacity and antiquated loading mechanisms. The use of modern technology such as motorized vehicles is frowned upon.
Ok, I can see that - although we have some idiots from the East Side (Redmond/Bellevue/Renton Seattle area) who come over to the Olympic Peninsula to hunt cougars with 7mm magnums (we take them with 30-30’s)- they leave soon enough when the local guys (and some gals) confront them ...
