Help - what kind of die to bump neck / shoulder

[DWN]

I have a 6mm AI that i fire form using 6mm Win brass. The neck shoulder junction to the base of the case in the 6mm AI is .01 inch shorter than the unfired 6mm Win brass. I have to bump the 6mm Win brass .01 inch to get it to chamber. Money was tight so i have been bumping the neck shoulder with a Lee 243 collet die. I resize fireformed brass with a Redding 6mm AI neck bushing die. However it will not bump the critical area of the new 6 mm Win case. I called Redding to ask what die i needed. The Redding tech recommended a full length die but could not tell me if i should us a 6mm Rem die or a 6mm AI die. The tech also could not tell me if the length of the 6mm Rem die from neck shoulder junction to base was longer that the 6mm AI die. If i had to pick one i would say 6mm AI. I also don't know if i will need to change or alter the shell holder to get the die to bump the neck shoulder area.
I also called Foster and the best the tech could do was suggest that i send my reamer in and have a custom die made. But lead time would be 14 weeks. May i have you advise as to which die to use. Thanks DWN

Call Redding and ask Dave Dibble to look at your reamer print and he can compare it to the die you are using. Dave can tell you whether you need to use different shell holders to be able to bump the shoulder on your 6mm Win brass. If that will not do it, he will have you send the die in and they will take a bit off the bottom so you can bump the shoulder.
