It is perfectly legal to have an empty case with a bullet seated in it, unfortunately I don't have any bullets I can send you for .44 magnum cases as I don't use this calibre. I can however send you a few cases and bullets in other calibres to pass on to your daughter. I am sure I have .308, .303, .38SP and .223. Drop me a PM if interested and I will see what I can find.
PS Mark, if you don't get any offers from this section rerun your post in the reloading section.
