Lube Dents?

5.56 prep on a Mark 7 driven Super 1050 at 3500ish RPH. I just switched to the carbide RT1200 size trim die using Dillon Case Lube.

Most cases that come out with a shoulder dent. Can’t figure out why. They don’t seem over lubed (too much lube is never bad. Lol). I thought the case may be hitting the trimmer too hard and trying to buckle but these are the only marks if any on the case. I would think if it was trying to buckle it would be more concentric. All thoughts appreciated. Thanks!

You probably just need to clean out the die. It sounds like it's just an accumulation of lube. You're loading 3 times faster than b hand, so cleaning and maintenance need to be more frequent as well.

It’s brand new as was squeaky clean before I installed it.

Suggest you post some pics

Hard to see with the lighting but each shoulder has 2 dents. These were smooth before the went into the die. Have a pic but there are no options for adding them. 🤷🏼‍♂️

Can you explain how you’d like the pic posted There’s no option to do so. Not even a copy/paste. Thanks.
