I dont know if u was having same issue as me but my dents were created from a starting load of us869 in the 7stw behind a 180,,, i read somewhere it was called collapsed shoulder... The next batch of 3 with 1grain more and it stopped doing it...
here is a pic of the 3 of them

was this from below min loads

i think there were a couple of things that contributed to mine...
neck wall thickness uneven ,,,new virgin brass,,and most definatly to lite a load for this combination. all 3 dents were different sizes.
would it do it again ? with fire formed brass neck sized probably not.
