7STW and Chaser,
The early 9410's were open choked, the later ones offered chote tubes.........However the open choke model 9410 I tested, shot full choke patterns.......How???? Choke is a matter of pattern performance not constriction. The standard constriction for .410's were developed and deterrmined early on when the hulls were brass or paper, the wads were felt and cards, the shot was near pure lead, and the crimp was a card overshot and a roll crimp. Guns like a model 42 or the old singleshots needed constriction with the type of ammo of the day.
Take the 9410 and pattern it against a model 42 or 870 full choke gun and I think you'll see it'll throuw as dense of a pattern.
That all being said, the .410 is a 25 yard gun in an experts hand. You might squeeze it out to 30 yards on doves or quail. I think the 28ga is much more effective at wingshooting, with it's 3/4 oz payload.
Lee24,
How many #2's can you stuff in a 410 3" shell, and what do you think a pattern/velocity at 60 yards would look like?? Someone might kill a mallard at 60 yards by luck with a .410, but not consistently. And 80 Yards?? Lead ain't that good.
