Ed,
I normally shot ic and mod in the 28 early season, then change out barrels with Improved modified and full. The 410 is choked m/f both are AYAs. The 410 is a #2 and the 28 is a #1, with two sets of barrels.

Thing is with that little 28, if your on the bird that little 28 smokes them dead every time. Heck a blind squirrel finds nuts. And trust me I have missed my share of birds. A lot of birds!
