From years of clays and hunting, I too focus on the target for close in and movers. For the longer shots I sight down the rib and focus the front bead. Something that hasn't been brought up yet is that I know that my SG fits me. To determine fit a person needs to assume your comfortable/repeatable firing position, look at a stationary target, close your eyes, shoulder the gun then open your eyes. If the gun is on target it is properly fit to you. If not, the handy set of stock shims that came with that Benelli can be used to help adjust for the proper drop and cant of the stock to put you on target. YMMV
