Rifled bbls excel at shooting Sabot loads at deer and other medium game and at nothing else. Very specialized, and part of the allure shotguns have is due to their flexibility.
For a dedicated deer gun, a rifled bbl will do fine, once performance is tweaked a bit and the best load chosen after range testing.
The 1300's a good shotgun,tho not my favorite. To do it all, you'd need the rifled bbl for deer, a short smoothbore bbl for HD, and a longer bbl for bird hunting and clay games. Most folks use a short smoothbore bbl, oft with rifle style sights for HD and deer, and a longer choke tubed bbl for birds and clays.
I suggest getting something more GP for a first shotgun, and leave the dedicated guns alone until later.
HTH....
