Larry;
Put your thinking cap back on for a bit. Fact is, at skeet ranges the 28 is capable of running near perfect scores, with misses being the fault of the shooter more so than the gun. "IF" one is breaking 98-99 out of 100 with the 28, then maximum improvement which would be possible would be 2% even if a 10ga with 2oz of shot was used.
Sort of like if I take a .22LR to the squirrell woods & kill a TN limit of 6 with 6 shots, I would not expect to have a higher kill/shot ratio if I carried a .32-20, But, on the other hand, If I were shooting Coyote??
Take the 28 & the 20 to a handicap trap range. Start at the 16yd line & keep baking up after firing a statistically reliable numer at each point. If the 28 seems to still retain the same effectivness, First pat your self on the back, You're a great shot. But be well aware it will have done so because of the afore mentioned central density of the pattern either from a higher percentage overall pattern or from an increased percentage of the central core thickening, Either which is accomplished at the expense of a reduced effective kill circle, there simply is "No Free Lunch".
