Mark,
You many or many not have the answer to my question (anyone else may chime in as well!), but I'll ask anyway. I've been considering the Express combo for a while now (just waiting on the funding to build up), and I was noticing in the Remington catalog that the combos come with the smooth bore for one, and either a fully-rifled slug barrel or an improved cylinder barrel. So I ask (as I let my ignorance of shotguns shine though), what is an improved cylinder barrel, and what is it used for?
Thanks!
