Certainly to each his own, but I'd just as not have the rifled choke. (No. I'm not giving it away though.
I've the 870 Turkey - all 'round favorite. Comes with the extra full choke & I grabbed an Imp & Mod choke - seems to cover all the bases.
Bought the rifled choke to try the spiffy sub-caliber sabot slugs = key-holing at 25 yards/accuracy sucked. Settled on PMC's Brennekes which shoot just fine through the modified choke.
The "high-tech" slugs are way expensive & while you have the rifled tube installed, your shot patterns will likely suffer.
My favorite all 'round choke is Mod & with that, I can shoot slugs & all shot.
