I've read many times how tough African pg are to put down and I've often wondered if there's any truth to it or if it's a self perpetuating myth.
Are they really hard to put down or is it that people believe and hear they are, so take larger calibres that they're not comfortable with believing they need it, put a poor shot on because they can't confidently shoot the rifle and then have a big follow up therefore confirming what they've heard?
I ask because we have the exact same thing with sambar in Australia, which a very big animal. People always talk about how hard they are to put down so guys go after them with 300wm and up as a minimum, flinch at the recoil, hit em in the guts, and maybe once up the arse as they run away never to be seen again and think "sheet they're tough". Whereas I've put more sambar down with a 270 and 130gn projectiles than anything else. Biggest follow up was 100 metres, most die within sight. I shot a lot of sambar with 300wm, 9.3x62 and 30-06, none died any deader than the 270 shot ones. Sometimes wish I never sold her! Put a bullet in the boiler room and nothing will run too far.
I reckon 270 can handle pretty well any non DG on earth, and even there my old man and his mate hunted water and buffalo with a 270 back in the 80s when farmers welcomed you on to their place just to shoot the buggers and had no problems.
