If I wanted a 300 WM for a hunting rifle, and that's why it's important to have an intended purpose, I would give a different answer than If I just wanted to shoot holes in paper, or ring steel.
For a hunting rifle my choices would be a Ruger Mk II (preferably in a skeleton stock--Zytel), a Weatherby Vanguard, or a Winchester mod 70 Classic stainless. Maybe even a Kimber Montana.
I'm not a paper puncher exclusively so others can speak better to that, but you have my picks.
