[QUOTE="Jcann, post: 2921673, member: 33119"] I have a chamber neck diameter of 0.320" in my 7mm and a finished case neck diameter of 0.313". That's a total difference of 0.007" or 0.0035" between outside neck and inside of chamber. This workers fine for me with my rifle but you probably would not want too much "room" between outside neck/inside chamber or you'll over work your brass. I anneal after two firings. I also use Redding type S dies with a bushing. I assume you're set up likewise. I also use a K&M neck turning tool with a cordless drill (slow RPM). If your using a bushing seater die you may want to try two or three different bushings. There is an execellent article on Accurate Shooter with regards to neck turning, I'll look for it and post the link tomorrow if you would like to read it. [/QUOTE]
