For slug accuracy out of a smoothbore shotgun I have had my best luck with Winchester pumps. I've used the Ranger model 120 for 17 years and also the winchester 1300 (though neither are being made any more and are both kinda ugly). These have both shot remarkable with winchester super-X slugs. I actually ground stand hunt with a scoped winchester 120 and it is right on at 100 yards, though I would not shoot any further. If I'm walking I carry an Ithaca deerslayer smoothbore which is also quite accurate with super-x's and extremely smooth shucking,lightweight, fast handling and reliable. If deer are being pushed to me I use an 1100 (with Super-X's), though obviously not a pump. I am very lucky all 3 guns shoot the same ammo well, it makes hunting a lot easier. I personally feel a used ithaca with a deerslayer barrel is about as nice of a dedicated deer gun as you can find. You should be able to find one for $250 -325. The only negative is it is a lighweight gun so it kicks something fierce. I also have extensive experience with my brother's Ithaca Deerslayer II (rifled barrel), which is a great shooter with lightfield slugs, but has had problems cycling the 3" shells. They run about $550unfired (if you can find one), so they may fall into "break the bank". Just my 3 cents
