    Not sure what got me checking but I came across something with my Lee 22-250 FL resizer die. I got to measuring the opening at the bottom of the die and checked all of my dies that are all using the .473 bolt face including .308, 6.5CM, 6mmCM, 6mmBR and my 22-250. What I found is the opening on most of the dies measure right around .468 but on my 22-250 die it measures .457 and this makes me wonder if that die is made wrong. My books show the brass for these other calibers at .470 and the 22-250 at .467 but that die is still .010 under at .457 am I missing something with the 22-250 or do I have a defective die?

    Here are the official SAAMI dimensions for both the case and the chamber:

    I have a few die sets in 22/250
    Redding body die---- .457
    Forster FL---.464
    RCBS standard FL----.462
    RCBS Comp FL sizer----.456
    Keep in mind this was measured with an inexpensive vernier

    Are you using pin gages or hole gages and a micrometer?
