My father just gave me this gun for deer season. It is a smooth bore and a rifled barrel is cost prohibitive at this point. Can I run slugs down this barrel and if so should I use rifled slugs? The gentleman at Gander said that rifled slugs should do just fine in a smooth bore, also should mention I'm not planning on running boxes of slugs through it. Got a trip planned Thursday evening. Thanks in advance for any replies.
