Could someone with some 30-06 lapua brass measure the diameter @ the web right before the extractor groove (case head)? I have been using winchester brass in my custom shilen chamber and I have had nothing but problems with primer pocket expansion. All the WW brass I have measured is .462-.464 in this area and my chamber is right at .470" factory spec. Just curious if Lapua brass is closer to .470". Thanks this is for my 25-06 AI.
