This is a long shot and I know your dies, cases, etc are already on the way. But just so you don't have similar issues with the Hornady dies, check the shell holder you have. From the surface that the case head sits on to the top of the shell holder that would touch the base of the die should measure no longer than .125". Less than that and you can adjust your dies accordingly. But longer than that it restricts the distance the brass can go up into the die. Do I think that if your shell holder is out of specs that it is the root cause of your issues... No, I don't think so. But if you bought a set of dies that were on the high side of Redding's tolerance zone and a shell holder that was on the high side of thier tolerance zone and your brass was a little on the thin side of their tolerance zone... all of that added together could easily add up to what you are seeing. It's called stacking tolerances if you have ever worked in manufacturing. If you have and you are familiar with it, sorry for the duplicate info.
I had a Lyman shell holder for 223 30+ years ago that was way to long (out of spec) that I had issues with. We always assume shell holders are a simple object and really don't check them. But it is part of the overall system and an important one. Just something to check and make sure it not a contributing factor. Please let us know what Redding comes back with.
If this is a shell plate on a progressive then this is a little different measurements as the shell plate doesn't dictate the same distance. but if the shell plate is too think overall it could restrict the distance the brass goes up into the dies. I don't have those specs off the top of my head. But I use a Hornady AP so if you use the same I can do some measuring of the 40S&W shell plate/setup and we could compare numbers. If you use a different brand progressive them maybe someone else could help if needed.
