Wait a second I was just looking at something, if I have the 11-87 sportsman 12 gauge, do I need to go buy a new fully rifled barrel, such as a Remington cantilever scope mount barrel; or can i just buy an extended rifled choke, and put the extended choke in and shoot sabot slugs for deer? What would everyone advise doing money isn't an issue so basically if someone could tell me the difference or what to get that'd be much appreciated!
