Extremely effective. Out to 35 yards you don't need the extra horsepower of 3". I shoot the Remington 2 3/4" 000buck. Pick one and pattern it before you hunt. Also try different chokes. I use a skeet choke in my 20" Rem 870 barrel. I get 8-10"patterns at 40 yards despite the "looser" choke than improved.
My brother uses the same load with a modified choke and gets about the same pattern. So don't be afraid to go up or down as needed.
Have fun and good luck! Thanks, Tom
