Blue wings and Canadas are common mixtures around here at this time of the year. I've been using #5 Bi on both, but when I hear them coming and have time, I like to swap out shells and go with heavier - usually #2 Bi -for Canadas. But that's for my guns.

I just don't know what is workable in modern o/u's with damage to their muzzles.
