I have a Remington 870 20 gauge with a full rifled barrel and a Mossberg 935 12 gauge with a full rifled barrel.
Remington Premier cooper solids were my choice till I tried Remington Accutip slugs.
They are great.
Very, very fast and very, very accurate.
They shoot very well for me out of both guns.
I am in a 3" circle at 100 yards and I wouldn't hesitate to shoot 130-140 yards.
