The "Search" feature on the forum is a great tool to find old posts that were made about some subject. We've got posts going back over 18 years and because muzzleloading doesn't change much, many of those old posts are as good today as they were when they were first posted.
That said, if you are reading some of these old threads and you want to comment on something that was said, please remember. The person who made the post might have left the forum. Even if they didn't leave, the chances of them remembering something they posted 15 years ago is very unlikely.
