based on shawns statistics which seem reasonably correct- do the better trapshooters have 2 differant yardage guns? i never see anyone making adjustments, be it comb, rib or chokes for that matter! i think this past year i read from kiner or hoppes columns that you shoot them the same -speed sight picture ect? but i dont remmeber them mentioning 16yd vs 27yd gun changes?
