You will probably get OK accuracy for a few shots, but as the rifling get leaded the accuracy will diminish and it will be a pain to clean out. That being said a lot of folks use cheap slugs in the sighting proccess,kust to get on the paper. If you want to shot cheap rifled slugs just find a smooth bore barrel and blast away. I wanted to do this so I bought a used barrel and chopped it to 22" and it is a good 50yard slug gun. It has become the gun that stays in the truck and goes with me any time I'm just out walkin in the woods.
