[QUOTE="QuietTexan, post: 2533811, member: 116181"] There are two very distinct conversations happening in here. 1. How to resize before case stability is reached at ~ 2-4 firings 2. How to resize after case stability is reached at ~ 2-4 firings This is the answer to 1: This is the answer to 2. This is the combined answer to 1 and 2. "Bump neck size" is an accurate description because the Forster bump die doesn't size the case body, but since the shoulder is moved this is still commonly NOT referred to as neck sizing. If case body sizing is needed when using a Forster bump die then a Redding bushing die or body die can be used on the body, or a standard FL die not screwed in all the way can work the body somewhat. Someone else already mentioned the Willis collet die if there is a case problem isolated to the web directly over the belt. You'll notice for both questions there is never an answer of "set the FL die at tight as possible" because for a 300 WM there's no reason to set the shoulders back that far, all it'll do is cause you to trim a lot and most likely set you up for a case head separation.
