I don't have the rifle chambered yet but was preppeing some brass last night. As normal, using the Redding bushing FL sizer I get a small section of the neck unsized. Normally not a problem with correct brass, but when forming, will this cause a problem in chambering? Or will the camming force of the bolt be sufficient to squeeze things in place for the first firing? Or do I need a standard FL die for forming? Thanks!
