anyone need 4.6x30 brass

[fast54vw]

i have 15 pieces of 4.6x30 brass that came mixed in with some 5.7x28 brass i bought.
ive never even heard of it before but if someone needs it its theirs.
after looking on the internet it fits a H&K MP7 & UCP pistols & it looks like its kinda hard to find

I'd like 2 or 3 of them for my cartridge collection...
