    Mine is a match reamer, and has a .319 neck. Setup for 300SAUM Norma brass necked down. Needs a very light neck turn.

    I haven't tried a 180gr in a case to see how it measures up, but with a 162gr amax it measures 2.995 OAL to the lands. My reamer specs show a throat of 2.250" and leade of .188 if that is any help?
    If it's not a first round hit you need to practice more

    Thanks for the info, a .319 neck would be too loose for my liking the nosller brass with a 180 Berger in it measures .3142 with a micrometer I normally keep my clearance to 3 thou

    Cheers
