Iron sights, I can live with 3 to 3.5" 100 yard groups for hunting. I try for better, but can live with that knowing that I will only take a shot that far with irons under perfect conditions.

With a scope, I want 2" or less, but will live with 2.5". Like Sabotloader, I don't mind giving up a little in group size to shoot the bullets I have total confidence in (i.e. Gold Dots/Deep Curls).

There's only one stand in my hunting area where I can see out to 175 yards. A few offer 150 yard shots, but most are right around 100 yards.
