[QUOTE="woods, post: 268155, member: 6042"] Hey cross One thing you need to know about the Forster Bump Die is that it does not size the case body. Now I do not know this because I have one but was wondering if it did so I e-mailed Forster and got a quick and short answer from Dee in customer service. Still concerned I asked her to ask my questions of a tech and got the following reply "Dee referred your query to me and here is ,hopefully, the answer to your concern. Your question is important to us. You mentioned that you "were leery of creating a bulge in your case body". Answer: The body of the Bushing Bump die is designed to push the shoulder of the rifle case back only .001" or .002". This is just enough to support the case and to keep the body of the case in good alignment while the neck of the case is being squeezed down to a smaller dimension. If one were to try to push the shoulder back much more than .002" you may develop a problem with case "bulge". Best regards and good shooting, Bob Ruch @ Forster Products Inc." What this means is that when your case grows and you need to size the case body then this die will not do it. Unlike the Redding Bushing Dies which will size the case body unless they are the Neck Sizing Bushing Dies. Perhaps you will not have to size the case body but I have found that the case will start to bind after several firings along the case body in most cases. The Redding Body Die will push the shoulder back and size the case body (unless you have a minimally sized custom chamber, don't ask me how I know). With the Lee Collet to size the neck with minimal runout and the Redding Body Die to size the case body and push the shoulder back you will have a good set of dies to neck size when you can and push the shoulder back when you need to. However, the Lee Collet neck sizer does not give a lot of bullet grip, only .001" to .002". If you can't or don't want to live with that then the Lee Factory Crimp Die is a good solution. [/QUOTE]
