Ran into the same problem. I reduced the gas flow until the problem was rectified and never attempted to reload the damaged brass.
Shoot them if they chamber. The firing will iron out the wrinklesHornady 6.5 Creedmoor brass out of a Dessert Tech MDR (semiauto). The location of the damage has me concerned. I'm not looking for precision loads. Just looking to load some practice rounds, 200 yards max, but I don't want risk catastrophic case failure. Any thoughts? Thanks!

To look at dinged up brass, look up what an HK91/PTR91 does to brass. I had one and it would beat the snot out of brass.

How new is your MDRX? This seems to be a common problem with MDRs, at least in 6.5CM. The problem happens when the round chambers, regardless if new or reloaded brass. At least I've had this happen with Hornady, Winchester and Sig Sauer New brass straight from the box and loading it without firing it to see what was happening. I've been told over time this will correct itself from DTA... my thoughts are they still have problems with less than optimal machining and engineering that we're beta testing for them. I have less than 300 rounds down range so for now I'll give it some time to break in. If the dings don't smooth out after resizing them, then I'll probably toss them.
DTA is well aware of this issue and for the moment they are blaming it on 'soft' brass. I don't buy it. It's also not the forward eject system. I've taken it off and let the rounds side eject
And the brass still has the marks. As noted above, I think it's the feed ramps. But can't prove it yet
Spot on. That totally escaped me but you are completely correct.Can't be happening when being fed. Because they would be gone once fired. It has to be happening after ignition.
