Well the only slugs i would be shooting are to sight it in as best as i can and for deer season. Its a quick fix until i can get the money to either buy a rifled slug barrel ($148) or an Ultra Slug Hunter. Best case scenario is i can trade or sell my gun and use it towards a rifled slug barrel.

*Edit* I have found a Rifled Choke Tube that is compatible with my Mossberg 500, will this make it much more accurate? And can i fire sabots out of it or just rifled slugs?
