I just returned from a six day shoot on dove in Argentina. I used a 20 and a 28 and I was disappointed with the 28. Now given that the shells were number 7's in the 3/4 oz 28's and 7/8 oz 8's in the 20 you could argue that I'm comparing apples and oranges. The 20's modified choke compared well to the improved modified of the 28. The birds were not easy and most of the other shooters found the 20 gauge modified to be best. I love shooting the 28, but I'm beginning to think it is a great short range/skeet gun.
