If not a hand loader, then 300 win mag. I have recommended this cartridge to guys who literally wanted one rifle and aren't in to tinkering. There are more factory rifle choices in 300 win, but the 300 wsm is a great cartridge . Do a search for Broz, he is hands down the expert on the 300 win mag for hunting and ballistics with real ranch data to back up his conclusions[/QUOTE
