Other than the empty cartridge I cut short and hammered into the top, as a memento of many years of fine shooting trips. An old Freedom Arms loaded 454 Casull hull, originally shot off many years ago out in Nevada. Good karma in spades.
Now I see this on the internet. Maybe I ought to spend some time in the Man Cave, with a whittling knife and Dremel tool, putting a nice Odin's face like this on it?
Oh, yeah I will.
