It should iron out the loaded round by using a Lee Factory Crimp Die with the collet removed like the Redding GR buldge buster shouldn't it?

If you seated the bullet past the ridge, then used something to smooth the outside, you would push the ridge into the bullet, and who knows what that might do to pressures.
He needs the expander to not go in past the ridge, and then not seat the bullet past the ridge either, as intended by the brass/ammo makers.

Good point Walkalong. I have yet to experience any high pressure signs but I only load light loads for plinking in 380. I see where it could be a problem closer to max but so far with the 115 gr. XTP's and 125 gr. swaged bullets I like to use they still appear mild.

I know what I'm looking at because I've personally seen the same thing with Federal .380 brass in my press. If the expander goes too far into the case, it pushes out the case wall exactly as pictured.
I would strongly suggest you pick up some Federal .380 brass, with the bullet stopping ledge on the inside of the case, and run them through your dies. When you have some personal experience with them, then come back and give your results.

Because a lot of .380 cases are tapered just below the mouth, being thicker. I had that problem when belling .380 cases that had been trimmed to proper length using RCBS resizing dies and the expander button after resizing.
The case would expand a bit too deeply, RCBS sent me a new expander that does not go quite as deep into the case in order to bell the mouth sufficiently to set and seat the pill.
Take a case that does that and run your calipers at the case mouth and in a bit and in a bit further and you will find there is either a ridge in there and/or the case metal tapers thicker as you go down to the base.

918V,
I fully admit to adding to the confusion. My first post #1 picture was a messed up reload and I shouldn't have been so quick on the "put up post" trigger. The picture in post #13 is the modified after making necessary corrections. This was my first go-round at trying to reload .380s and I'm new to reloading in general.
