I called Cabela's again today and found out rhe following. The gun comes with one each of the following tubes: X-full, modified, and improved. They sell and stock full, and modified tubes for about $18. The gun will shoot sabots but the guy had no idea which ones or where to get them. So more research will be required on the topic of sabots.
I think I will shoot PRBs rather than sabots but I will still try to find out what I can. The more info the better.
Now I have a question about shotguns in general to any of you that may be checking this thread. Afterall, QTomkins2005 and I can't keep going by ourselves forever. Anyway, the question I have is this. If I shoot a PRB or sabot in a smoothbore 12ga, what choke tube should I use? I'm thinking improved cylinder because it has the least amount of restriction. What do you think?
