Just interested in a little feedback. I have a Remington 870 .20 ga. rifled barrel slug gun. I tend to hunt heavy cover (like bow shots) so not too worried about getting a bead on something that close, but I think a scope would be nice to pick out holes in the cover too or stretch my shots comfortably to 75 yards + a little I suppose. Do you figure with the rig I have a scoped set-up will drill them right on target a whole lot better? I ask because I don't have much experience with these new hotshot sabot loads. The Hornady SSTs, w open sights, I got to group 3" more or less with the open sights at 50 yards. Any reasons for or against? Thanks!
