You could sure try, stalkingbear.
I don't shoot .460 S&W, so I wouldn't buy a stock, but you could also advertise on this site.

The best idea if you do it would be to put an ad in a pistol hunting magazine, or big game magazine.

It might be expensive, but it may just pay off, you know, you could put it in the same place where they advertise cheap camo, and gun racks, turkey calls, whatever.
