I know that you like this cartridge, and are probably set up for reloading, but there are several ballistically acceptable choices that'll have superior terminal performance in a hunting rig for the contender. The 35 remington comes to mind, or the good ol' 45-70 if you like the big bore stuff. Plus, these kick a little less.
Have you tried the 209 45 ml barrel? Not as heavy a hitter, but a riot to shoot.
