1. Some fixed choke barrels can have screw in chokes installed.
2. You can shoot any size shot you want out of a full choke and it won't blow the choke out.
3. A slug shot through a mod. barrel won't blow the choke out.
4. Buckshot will or won't mess something up depending on how tight the choke is. Everything but a turkey choke should be alright.
5. Imp. cyl won't hurt anything when shooting slugs,in fact it is one of the best chokes to have for shooting slugs depending on the gun you use.
6. Always have a choke in the barrel when you are shooting, the gun won't blow up or anything but it is hard on the choke threads in the barrel.
I hope that solved you problems.
