Well, what do you mean by "properly expanded"? I run the expander die down just "enough". It expands the case mouth enough so I can easily insert the bullet about 1/16". I do that and seat the bullet the rest of the way using the seater die. This seems to maintain neck tension and increase the life of the brass. If I expanded the brass so much that it wouldn't chamber in a Glock, isn't it "overexpanded"?
