What’s your budget range? There’s a lot of rifles out there nowadays that can pretty consistently send them accurately. Your glass is going to be a very important part of the equation and not going to be cheap. As far as the cartridge 300wsm is not a bad choice but I’d probably lean towards a 300win simply for the fact there’s a lot more ammo off the shelf if you need it. If I were going to reload all and wanted to kill stuff out that far I’d probably go 7mm ultra or 338 Lapua.

Interesting topic..
