You do not do a lot of walking on the cull hunts, because if you do, you will not get a lot of animals. Walking for a single buff means you miss out on a dozen further down the track.

Sight them.

Jump out.

Blaze away. Reload. Move a bit, or run forward to a better position. Bang away again. And so on, till the smart ones are out of range and the rest are dead.

Generally most of it was in range of the track. Not real hunting, it is why I referred to it as culling. We did do some walking - eg the scrub bull was hunted properly, and a few other times. But definitely different to the trophy buff hunts I did.
