always used 28" or 30" on my wing shootin guns...i agree, they wing better IMO.

for my turkey and now fur getter(predators) i love my 21" barrel on my 870.

though any wing shooting i do this year will be with it...either that or the old mossberg with a 28" but i am going to dedicate that a slug gun...my my 870 will stay turkeys and predators and buy a nice semi or o/u next year for my wing shooting needs...
