There really isn't to many hunting bullets in the 6.5 that I wouldn't chase elk with. Put a decent bullet where they live and they won't go far. I generally shoot the heavy bullets just because I think they look so freaking cool! Certainly not the best quality in a hunting bullet I know, but they haven't let me down yet. My one elk killed related above was laser measured at 273 yards after the show was over. They day after I shot my elk I was tracking a huge wounded mule deer that my dad had shot. When it came up at about 40 yards I threw my rifle up and broke the shot when the crosshairs hit the rear ham. We didn't recover the bullet but it made it up into the vitals. Had at least 3 feet of penetration and figure the Barnes will probably have more penetration then that.
