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.
