Is a smoothbore with rifled slugs good to go for deer or will you be really limited on range? Unfortunately rifled barrels for my nova almost cost as much as the entire gun.
I've used a smoothbore with sabot slugs before, accuracy is OK to 50 yards (150 feet), would probably still be OK to 100 yards (300 feet). Using a rifle is OK here, but when in the woods, most deer I've seen were less than 100 feet.
