I have a 26" barrel with a mossberg C-select type choke that is plain ugly. As I understand, slugs ought to be fired in improved cylinder or open choke. I am not going to use this barrel for anything else so I was wondering if I could simply cut the barrel back to 24" with no choke at all. What type accuracy at 50 yards could I expect. I would use this gun for hog hunting in the bush. I also thought I could epoxy glue on some open type rifle sights.
