Sorry to keep beating that old horse, Son, but you know how I love a mystery.

Back to the RCBS example, you can see here that their expander ball is the same for the Swift as it is for the 22-250 and other .224 rounds. (The same is true for their carbide expander balls.) So if you happened to be using RCBS dies instead of Hornady, your problem would be even worse.

I still question the temper of the case mouths. Every Winchester case I've bought new was slightly pinkish at the mouth, meaning it had been tempered properly. It should not spring back so much that you can't seat a bullet without shaving some copper.

Be sure to let us know what the Hornady rep says.
