Mark; ditto ss7 and royinidaho. If you don't anticipate shots over 500 yds, you're in clover. Otherwise, I would shut down at 600 yds because of trajectory and drift. (see my signature).
I'm a lot less picky on paper targets and in fact I used to shoot with a High Master who used a custom .280 Rem for his 600 and 1000yd Any Rifle. He won or placed in most matches he fired.
Try some 160 gr Accubonds.
Personally, I prefer the larger magnums because I'm a lousy wind doper.
Goes double for hunting. If you screw up on paper, no real harm done, but a lousy shot on game will ruin a trip, or the whole season.
Good luck, Tom
