Trap and skeet stick with 2 3/4, your limited to a max of 1 1/8 oz of shot, no larger than shot size # 7.5. Gun fit is important, so if your gun fits stick with it. Apparent lead seems shorter with a bbl of 26" or 28". 3" chamber is fine, gives versatility from clays to hunting applications ( I recommend 3" for this reason). Also believe in "shoot one gun/platform and know it". BIg Believer in pattern boards, skeet 21 yds, trap 40 yds. Screw in chokes a plus, change game , change choke. What else--oh yeah focus on leading edge of target and HAVE FUN!!!
