This question is prompted by "curiosity" ... not "bad results", as I'm getting the desired shoulder bump, solid accuracy, and single-digit SD's on everything I'm reloading using my Redding Type-S Bushing Dies. What I'm seeing is the bushing is contacting the case neck down about 80% of the way to the shoulder, and not sizing all the way down to where the shoulder starts to angle out to the case body. Is that expected and what the rest of you guys see, or is there something different I should be doing to get the entire neck ... mouth to shoulder ... sized by the bushing? Given the results, I think I'm OK, but I just wanted to stress-test that assumption.
You can see what I'm talking about if you look closely at the change of shading on the 300-PRC case I just ran through the die ...
