Watched  a 3-gun shoot and now I have some questions. When firing lets say 00-Buck, Sabot slugs and 7 1/2 size bird shot during the coarse of fire.....What choke do you use? The shoot required different ammo for different stages. Can I use a MOD choke and shoot slugs as well as buckshot/bird shot out of it with out tearing up my new Competition Master barrel? Do I run the rifled choke tube and shoot bird/buck shot  out of it? I simply do not know what choke tube to run when you have to shoot three kinds of ammo in a string of a shoot and not tear up a $800 shotguns barrel.  Thanks for any advice....Trapfan

Mike103,
 You have NO time to change chokes. You transition from rifle right to the shotgun. You then have to hit clays in holders at 20 yards then reload with slugs for steel poppers at about 55 yards. I just don't know if its OK to shoot slugs out of a screw in choke that is not slug specific. Or if you can shoot buck/bird shot out of the rifled choke with out causing harm to the barrel or choke.
