    Can anyone tell me what the case neck thickness is on their Nosler 300 RUM brass? I need the loaded round diameter. Thanks.

    I purchased a box right after it became available. My lot number reads: 113311331130. I measured 5 cases and this is what I came up with for neck thickness.

    Case 1 - 0.0138" - 0.0145" Average case thickness - 0.01415"
    Case 2 - 0.0138" - 0.0148" Average case thickness - 0.01430"
    Case 3 - 0.0130" - 0.0149" Average case thickness - 0.01395"
    Case 4 - 0.0131" - 0.0149" Average case thickness - 0.01400"
    Case 5 - 0.0132" - 0.0148" Average case thickness - 0.01400"

    Average thickness for all 5 cases - 0.01408"

    Hope that's enough information for you. I don't have any loaded rounds to measure, just empty cases.

    Thanks Kevin. My Rem brass measures .337 loaded, sounds like this should be close to the same at .336.
