450 Marlin Brass

Hey, guys long shot here, I'm looking for 450 Marlin Brass, preferably once fired. Things like this are near impossible to find now but figured I would throw it out there. I did find 20 on GB the other day & paid close to $2 bucks each shipped but I have some coming my way at least. I talked with Hornady & they "say" they are still making/offering it but I'm sure it's waaay down on the list of things they're gonna be making in the next year or so. Thanks & let me know if any of you have any stash or connections, LOL
PM me here will be fine, Thanks.
