Yildiz 410 O/U
It also depends on the choke you are using. I know that almost all of the fixed choke 410s were made full choke, but todays 410s come with tubes. I have a Yildiz O/U with screw in chokes and hunt quail with it using IC and Mod chokes. Works fine out to about 30 -35 yards. As a kid I hunted with a Win Model 42 pump that is full choke and it would reliably reach out to about 50 yards.
I also use my Yildiz O/U .410 GA for quail...and I practice at 25-50 yards for clays...the effectiveness range is impacted by the difference between 2 1/2 and 3" shells.
I find that IC and MOD tubes work great...and I get great quail hunting drop effectiveness at 50 yards when I use 3 Inch loads (7.5oz)
Plus the light weight of this shotgun is a huge benefit when I get toward the end of the hunt...where as my 20GA O/U is about 1.5 pounds heavier and a lot heavier to carry over a 4-5 hour field hunt.
Now for Dove season...the 410 is my go to weapon...and very effective even with 2 1/2 inch loads. Not bragging, but I had a double-double with it last Dove season...so a .410 works well for my purposes.
