I am also in the market for a 3-barrel combo, as I have usage for all 3 and it sounds like a bargain.
I am considering either the Mossberg 500 (pump) or 930 (semi) in the 3-barrel combo. Is the accuracy with the rifled barrels a common issue, or just something you've experienced with whatever combo of slugs you found?
In our area, shotgun season is the same as muzzleloader, and a buddy of mine (fellow CGN'r) is into muzzleloaders, so I figured this would be a good option to join him. Typical ranges would be 50-75 yards.
Dumb question: Do the barrels not in use need to be in the safe? I assume not, but wondering... since they'll take up some room and potentially get knocked around a bit.
