It is no problem to put 9mm brass in my 38 super roller size plate.
I do that with all my 9mm match ammo.
But this is in my plates.
My 38 super comp plates is tighter so I do not use them to roll 9mm.
Base of 9mm brass in 9mm plates: 9,85mm (0,388")
Base of 9mm brass in 38 S plates: 9,75mm (0,384")
Base of 9mm brass in 38SC plates: 9,70mm (0,382")
