When my grandpa passed away he left me an old 870 wingmaster 28" barrel modified. I've always wanted to shoot one with it. You guys have any idea what a good shell choice would be. 2 3/4 only.
See if you can get ahold of some of the 2 3/4 Federals with the flight control wad. Should be good out of more open choke, might try 4's.
Range will probably be 30 yards, but I bet you can find a shell it likes.
Appreciate it man!
