I used a 470 in 2003 to kill lots of game in Africa. Used Woodleigh softs on everything but buffalo. Shot a Eland thru the shoulders with a soft and it was under the skin on the off side. Weight was 492 grs and was as big as a quarter. Pretty good as the Eland was as big as the buffalo. Shot buffalo with Woodleigh solids and none stayed in him. I'd shoot softs if in herds. Softs shot thru wildabeast and kudu on broad side shots. Either would work fine for buffalo.
