Only a few modern gun makers wander through the jungle of lock making. It looks intimidating and ,after all, you can just buy finished locks. To really get it you need to make a bunch of locks. Don't worry what kind of lock or what you might use it for, the lock becomes the project and each one you make is an experience. I teach blacksmithing and the last thing we make is a repeat of the first thing we made. The difference between the two is easily recognized and the progress of a two day class is very noticeable. SO, my suggestion is make another one, start with Siler and go on to some of the casting sets out there.
