My earlier posts here on the forum were about trying to decide on a rifle or a smoothbore and I have decided to get one of each after all the feedback I got. I posted in the rifles thread to try and get some help deciding on either a .40, .45 or .50 caliber rifle. However, in this thread I am trying to decide on a smoothbore. I'd like to get one that can do the job right. I don't really think I need a large shoulder cannon. Largest bore diameter to hunt things like Waterfowl is 10 Gauge and there is not a regulation on the smallest bore. Small game and Turkey can be hunted with anything. This smoothbore will act as my shotgun. I would use it for hunting squirrels, rabbits, groundhogs, turkeys, geese and ducks. I might also use it for deer hunting but probably not as much as a rifle. That all being said what is a good caliber to choose. I have had some people suggest .58 cal smooth which is 24 gauge and some suggest going .62 cal and up. I dont really know what I want caliber wise. I have always hunted with an "unmentionable"(term I have seen others use to describe non muzzleloaders), 12 gauge single shot smoothbore but from what I see that isnt a commom gauge size. If anyone could put their two cents in it'd be appreciated. Thanks for all the knowledge shared so far and thanks for helping me out everyone.
