Here's a great article by Lee over at http://www.singleactions.com. Hands-on, real world experience and results. Not just an afternoon of shooting by some gun-rag author with a "loaner gun" doing a review. It a great read. He also talks 500 Linebaugh. For those who don't know, the 500 Max/500 Linebaugh Long is a lengthened 500 Linebaugh. These are .510 bore handguns.
