Smooth bores are fun and can be pretty accurate with practice and working up a good load, most who try them get hooked from what I have seen, I just don't see them as a logical choice if a lot of your shot oppertunities are in the 100 yds range, but no one says you have to shoot at every deer you see, if you get a .58 rifle and work up a load for one of those modern bullets some folks like so much and add a spendy peep to the outfit you are likley to see deer out of the range of that rig as well. This hapens with anything you hunt with, it is kind of funny at times when we want a gun that will shoot out to 100 yds because a smaller bore is best at 50yds or so.
You are still going to see deer that are out of your range, I have come to the point that I just figure shooting out to 50yds, one gun will easily do better the other probably would also, but if i don't kill the first deer I see I can hunt some more the next day
