There's an auction coming up at:
<broken link removed>
They have a random box labeled "308 WIN" and another few stripper clips of unknown bottleck cartridges. I have no affiliation and won't be there, but I thought I'd let people know.
I will say there are some scalding reviews of this guy on the "all-knowing interwebs," but usually from sellers, not buyers.
They also had a few old looking cap guns if anyone's into toys.
