I haven't experienced a proper charge myself. My only experience is as follows:

- A friend of mine had wounded a bull buffalo with my .416 Rigby, and when he approached to finish it, the buffalo came at him. My friend turned and ran as fast as he could back to where we were. I snatched a .308 from a fellow who had his hands full with a video camera (that wasn't working), but by that time, the buffalo had veered-off slightly and stopped, whirling around to face my friend again. I shot the buffalo side-on on with the .308, and must've hit the spine, because he dropped. The buffalo chased my friend for about twenty metres, and maintained a distance of twenty metres behind my friend. The buffalo had been galloping, and my friend was sprinting.

- Another friend of mine had killed a scrub bull with his .375 H&H. We walked up to it, eyeing the accompanying scrub bull who was quite agitated about seventy metres away. I asked if I could borrow the rifle to kill this second bull, and started advancing toward a small tree just ahead to get a steady rest. The bull began to run toward us, but not directly; it ran in a shallow arc, and I hit it twice in the chest at about fifty metres as it galloped, and it crashed. I then put a finisher in. The ammunition was factory 300 grain soft points.
