What sort of caliber are we discussing here, and what's your typical ranges?
For my .25-06 I just put it 1" high at 100 yds. and I'm good for everything I do in South Alabama. Nothing too fancy. Same with my .300 (and .416) - but I put them both 1" high at 150 yds.
Generally 200 - 250 yards is as far as I shoot anything around here - beyond that there's just too much woodland "jungle", and I find that does just fine for me down here.
