My SP deer gun came with the rifled choke in it and also with a modified tube. I have never changed the tube. The rifled tube will shoot home loaded Lee foster type slugs in 3” group at 50 yards with a red dot sight. This is plenty good for where I would use it. As I rarely use it to deer hunt anymore, moved to Missouri Ozarks, my present thought is to get a ‘turkey choke tube’ and use it on them next year.
