Re: what scope is best for a .243
Any rifle can be very accurate with the right load. I'd say if you are able to shoot 0.5 MOA at 100 yards then you are doing well. Find out the BC of the bullet you are shooting, figure out the velocity, and plug your numbers into a ballistics program to get an idea of where your bullet will be out to your max distance. Then go out and shoot on paper out to that distance to verify the drop. Start practicing at these distances and you'll become a better shooter than if you spend all your time at 100 yds. Once you know where your bullet is at any of those distances, you'll be deadly on game. Then comes the game of fine tuning your rifle, optics, and gear. Back to the original question, I think the 16X top end is fine for the distances you are planning.
