I just have some second hand experience. When I was hunting with Dries Visser Safaris last summer there was a hunter in camp while I was there hunting Leopard! His shot was 17 yards, at night, and we recovered the cat the next morning. Leopards are Dries Jr's specialty and would be a good place to start. They opened an area up in Botswana where they said Leopards and Lions come into waterholes during the day allowing the possibility of shooting them during the day without bait. Joseph
