Similar to the 8mm Rem Mag, I have used a 325 wsm with 200 gr partition for an elk hunt, brown bear and multiple deer hunts. That round has always been good to me. I am dabbling with a 340 wby this year and will probably take it on an elk hunt in the fall. I have a control feed M70 gathering dust that I have been thinking about turning into a 416 Ruger for no good reason but just to have.
