dented cases

On the upstroke in station 2 the powder station, 1 out of 12 cases gets dented at the top of the case. I don't feel any resistance and don't know it's happened till I look. Why would it do this and so infrequently? Ruins my brass.

RE: dented cases

Can you post a photo? What caliber?
If the case mouth is rolling inward, the most likely cause is the shellplate bolt is not tight enough, allowing the case to wobble excessively. Test by pushing down on the edge of the shellplate between stations 2 and 3. If it feels springy, then the shellplate bolt needs to be tighter.
Also, use the chart in the back of the manual to verify that the correct shellplate/ locator pin combination is being used.
