Case Thinning (Too Much?)

How much case thinning at the head is too much? I've cut 3 cases in half that I can "feel" a groove with a paper clip. I can feel a difference in each. The worst is at the top and is also the one that separated.
Load data:30/06, CCI Primer, IMR 4350-56.5gr, 150 Barnes TXS, 3.280" OAL.
These have been full length sized twice and neck sized three times for a total of 5 reloads.

So my question is if you can feel any thinning is that too much?
