Okay guys my buddy just got this little 20 gauge. It is in great shape. It feeds shells properly and seems pretty accurate.

My question is it has what appears to be an adjustable choke on it BUT all the way or screwed out there seems to be no difference in the pattern???

Also, can he shoot a 20 gauge deer slug through this particular choke set up? I would assume no way on Sabots .. but what about regular slugs?

What am I not understanding here?
