I need some info from the sabot slug users. I have a remington 870, rifled barrel w/ scope. I just ordered the shurshot stock from remington with the new forend and a box of the Hornady SST and remington accu-tip. What can I add to the gun to make sure I get the most accuracy and distance? I have only used crossbow and a smooth bored slug gun lately to hunt and this will be my first year with the rifled barrel and sabot round.
