Jim Supica, the Director of the National Firearms Museum shot 30 rounds of .45 Schofield through Jesse James' S&W Schofield. The fired rounds and their cases were then matted and framed in a very handsome display for the Friends of the NRA auctions. I saw one two weeks ago at my local event. I thought it was pretty neat and I bid $300 but it went for $450.

There is also a video and perhaps that's what you saw?
