Not really. The "Rifling" of the bore will spin the shot and in a very short range(like 5-10 yards short range)the shot charge opens wide like a doughnut.
Instead of a nice collum of shot like a smoothbore spreading out for that pattern we're used too, ya git a big circle going out with nothing in the middle. :wink:
That, and the shot will very quickly fowl the rifling with lead and affect the accuracy of other projectiles ment for the rifle.
So it's rifle for rifle stuff and smoothbore for smoothbore stuff.
