Sounds Like you need to get a set of bushing dies from Redding and size only enough to get .002 to .003 bullet grip. Also an anneal may be necessary.

The other advantage to the bushing dies is that they don't overwork expensive brass.

I have uses standard Redding dies with a VLD seater, no issues. I use a Redding Carbide expander when resizing. I had minor issues with the RCBS dies prior, had to really clean and lube case mouth. Also clean the RCBS dies very often. You may start with a good cleaning iand new expander or inside case neck turning.
