The downside of having a shotgun chopped is that the chokes go with it,and you're left with a cylinder bore. Some folks think that it doesn't hurt,but I prefer a little tighter choke for knockdowns and those targets that are set a little far away. I shoot a Stoeger Coachgun,and it's a good shotgun. These guns,like a lot of CAS guns,benefit from some judicious gunsmithing to make the guns easier to open and to make the shells easier to flip out of the chambers. The Stoeger is a good choice for CAS.
