I like and shoot both smooth and rifled, but not a great fan of the 58 cal. for an everyday shooter. If I was hunting elk, bear, moose, etc. then 58 might be a wise option, but personally the .50 is my favorite. Ammo, ie. balls are a bit cheaper, easier to work up light loads, 30 - 35 grains 3f at aprox. 30 yards will just about duplicate a full charge of say 90 grains at 100 - 150 yards. Back in the day our club used this light load at our shoots and none of us had to change our sights from what we used for hunting. That load with a spit soaked patched ball and I could shoot all day long without having to clean the bore.
