Small Nut Wizard by Holt's

We have a pasture with about 8 oak trees in it. The acorns are 1/2 inch by 3/4 inch. Will this tool get it done? Will it take forever?

Will it pick up sweet gum balls?

Doe this come with the dumper tool?

will this pickup 9mm pistol cases? They are approximately 3/4 long by .391 diameter
