I have shot a few buffalo with my 303 for Dog meat. I buy the cheapest ammunition I can get from my local which is the Highland 150gn. Have had no issue with it and the one in this photo was a frontal heart shot from memory. Only thing is I have to use 2 leaves more on the sights than what I should but that is probably more a regulation issue than the ammunition. Either way they kill fine if I do my part. Sure it is a cheap type projectile but proof is in the pudding as they say.
