I practised once before an African safari shooting my .375 at longer ranges. It comes as a surprise when you see the bullet impact on the ground in front of the target. The amount of bullet drop was more than I expected. With that sort of bullet drop it makes a lot of sense not to shoot at those sort of ranges as it is not really practical to allow for that sort of drop in the field. Nowadays using a rangefinder would help, but still I don't want to carry a calculator around with me on a hunt. I find allowing a small amount of "light" above the shoulders enough of a range, not a lot of "light", it then just becomes a risky non-percentage shot.
