9MM RFL dies??

[jvm]

I have a set of Lyman dies in the black paper box.

I thought they were 9mm pistol dies at the store so they went home with me.

They appear to be rifle dies, after seating the net, I have failed to find out what they are.

Anyone know what they are for they are not marked 9X57 just 9MM RFL

I googled "9mm RFL" and most of the references were to 9mm Rifle (rifles chambered for 9mm Parabellum). Looking inside one of the dies, sizing die, is the interior shaped like a bottle necked cartridge?
