Do they shoot slugs on the shotgun portion? I do have an 1100 with a rem-choke "deer barrel" for it. I guess it would work out of desperation.
We shot slugs last month but I don't think we plan to this month. You can run that barrel but one with choke tubes would be better for the steel targets. We typically run a a light modified choke and shoot slugs through it as well. There is no reel need for front and rear sights to shoot the large IPSC targets with slugs a front bead and steady hand usually get the job done.
