Yes, the shot shell will harm the rifling. From what I understand they were used sparingly with the rifles. However some rifles were converted to smooth bores for this reason and were issued to police units and prison guards. I have tried it with my rifle and had terrible results with both buck shot and bird shot. The shot pattern is far too wide to hit a single target, however it used for say a riot, then they could be effective.
