Who cares how old it is? This info has helped my out and judging by the view count a good source of lead is something that is sought after when shooting BP.
I am almost tempted to say that a mod needs to make a thread listing all of the ways to get lead easily. That way it will answer the question that probably everyone knew person to BP wants to know. Even if you aren't knew there might be ways to get lead that you didn't know about.
