This is not a new problem and normally only shows its ugly head when target turrets are used. there are however older actions that have always had this problem, even with standard turrets. They tend to ding the case mouth during ejection because of the angle of ejection.
For those that are not in to much of a hurry, I am working on a simple fix that does not require a gunsmith to do anything. I do not intend to sell these and will show the membership or the Do it yourselves guys how to make one themselves or buy the parts for almost nothing.
A little more testing is all that required and it should be ready.
