I had to tune the pawl adjustment after about 300 rounds. Seems like the machine just needed to settle in a bit.
If you are denting cases like that, you are working the press too hard. You will break things and not have fun. The instant you feel more resistance than usual STOP. Figure out what the hangup is. When mine started occasionally failing to fully index on the way up, I stopped and figured out what the problem was. A touch on the shellplate popped it into position so I finished that run paying extra attention, then tuned the pawls later after doing research out here on the www.
Hope that helps.
