Yes to the distance question. The 3 1/2 12's and 10's in no 6 throw around 500 pellets. combine that with an ultra tight choke and you gain considerable distance. I shoot em at 30 yards or less. I wont push it any further with my 20 ga.
A buddy I hunt with pops em at 50 plus all the time. He rolled one at 70 yds with a 10. I would have never taken that shot, but he dumped it like a sack of potatoes.
