I'm not a hunter yet, but I bought the mossberg 500 combo at Dick's for $250 on sale. I've only used the field barrel so far for trapshooting. The rifled barrel has a cantilever scope mount, and a cheap scope was included. I figured you can't go wrong for the price.
I hopeyou let a bunch of slugs fly long before you hit the woods with the new gun. Your quarry deserves to be dispatched quickly and humanely. Is it the same gage as your old gun? Even if it is, a new barrel will shoot differently especially a rifled one.
