Improved cyl. with a smoothbore works best for me. Cheap old Remington sluggers did the best. 2 3/4". The box with 1560 fps on it. Not the max dram eq. ones. Reminton 870 with a b-square scope mount. It really shoots well. Good for about 80 yards. Last year I had Tru glo sights on it. (like Turkey sights). Killed one at 60 yards and the slug went right where it was aimed. They do not run!!!!!!!!
gotta agree with you there cuz. bought a iron sight rifled barrel for my mossberg 500 and i shoot 3" remington rifled slugs (1800fps?) and do kill at 100 yds in my thick woods.
