I'd recommend sitting in front of the machine and call in. The only things I can think of is that perhaps the powder adapter is screwed down a little too much and so when the cylinder presses up, the slide pushes all the way and there is no more give, so it would bottom out and crush the case. Make sure that the powder slide freely moves, if not then take it apart and make sure nothings burred or binding. If the powder dump mechanism is free moving and working, then I would think that it's is what I previously mentioned the funnel does not have enough play and is bottoming out.

I ran into this when I went from 9 mm and 45 acp to 223. I had to raise the powder adapter up so that the powder bar was not fully pushed over, then I slowly lowered the powder adapter until the powder bar fully cycled and there was no crushing.

I hope that this helps you.

I noticed the same problem a few years ago when I started loading 9 x 19 mm. You may be following the same procedure already, but since adding this step, I don't run into the same issue. Specifically, before I tighten the shell plate, I put an empty case in all four positions.( It is easier to do this with the toolhead not installed) I gently push down on the shell plate until all four brass pieces are snapped into place vertically, and then slowly tighten the set screw. Before, I was getting just enough slop (brass out of plumb) that the powder die insert was doing what you describe. I still check the alignment every hundred rounds before I make the final handle stroke, but this method has helped. I saw a guy do this on You Tube, so it's not an original thought. Hope this helps.

I am new to using Dillon, and have been experiencing the same issue. I first reloaded 350 cases of 357 mag with no problems. But now with M1 Carbine rounds about every 5th round or so, when in the #2 powder station a small section of the brass bends/peels inward. When it is working it flairs the brass perfectly, but occasionally it is as if the powder funnel is catching the edge of the case and bending a part of the brass inwards. Now after trying to reload 400 or so M1 Carbine, and losing about 30 cases, I'm frustrated and ready to go back to my single stage Rock Chucker.

jpb347,
The most likely casue for your case damage is the shellplate bolt is too loose. To determine this, push down on the edge of the shellplate between stations 2 and 3. If it feels springy, then the bolt must be tighter. It helps if you grease the underside of the head of the shellplate bolt, where it contacts the index sprocket.

Also you might want to check that you are using the correct locator button and that it's present. For example, if you removed the locator button at the powder drop in order to remove the case and weigh you powder charge...forgetting to replace the button will cause the issue you are seeing.

OK, it has been a month or 2, I have been reloading quite a bit. My shellplate was not lose, very little if any play in it. The grease did help it to rotate. The shell pins are the correct ones. I don't have multiple pins out when reloading, just one caliber at a time. As a side note, there is always going to be some very small amount of play in the case as it sits in the shellplate or else the shellplate bolt and/or pin hold the case so tight the plate would not rotate. These are metal against metal with a spring to add tension. Though I think Dillon would have thought to put a rubber washer around the shells pins to add a cushion which could have acted a pliable bumper to hold the cases in place against the shellplate firmly much like a tire adds cushion to the rim of a wheel. But that is another subject.
What I found is that the H110 powder that I use in M1 Carbine reloads is so fine that it was binding up the powder funnels. AT times I noticed the was not dropping correctly, to little was dropping. After some messing testing, powder spilling and such, I found that the funnel was sticking in the die. I could force the funnel up with my finger, and I felt resistance as it broke free. It would then go up and down freely for a few rounds and then stick again. I don't believe I have a faulty funnel tube or powder die, as I changed out the powder die with a different powder die. I have also reloaded with different calibers, 357 mag, and 223. and had no problems with the powder drop, the funnel tube sticking, or the cases being bent or sticking. For the 357 mag and 223 I used different powders, one a flake granule and the other is stick granule, both much bigger granules than the very, very fine H110 powder granule. The powder funnel sticking with the H110 was something that repeated several times. I saw a guy on You-tube have problems with the H110 spilling until he replace the smaller powder measuring tray with the larger tray. I was unable to try that because the load was too small. Not sure what the solution is to this issue, or if there is one. I have just received some more M1 Carbine brass and will try it with a IMR 4198 powder, which is a stick powder. I will let you all know if that solves the issue. Or I may run some shells through the first 2 stages and just bell them without loading powder and see if the same problem happens.

Thanks guys, in my haste switching from 45 Colt to 9mm I forgot to change the pins!! Could not figure why it was suddenly chewing cases til I read this forum post. Again many thanks
