I was wondering if I could use any make of shot gun choke for my Charles Daly shotgun.....will they fit? If they fit, what would it hurt? Also, this is my first go around with a multi choked shot gun, can you shoot slugs with them? Would you use the widest choke available? Last question.....the paperwork says not to shoot steel shot with the choke tubes that came with it......does that even make sense? Why not? Thanks for the help
