My vote goes for the Mossberg 500 with a cantilevered rifled barrel and a 4X scope. I used Remington sabot slugs and at 100 yards bench rest could touch the holes. Killed a lot of deer with that combo; in fact every shot even out to 110 yards was a pass though. However, do a lot of small game hunting as well and it got expensive re-sighting the slug barrel when I changed it out.
I bought an H & R which is just as deadly. Good stand gun but is a bear to carry around.
