Kinda, I have been working on a larger version of that bolt and I have been having some issues, although most of the issues I have encountered with a large scale version have to do with the materials not being able to handle the forces involved. With a larger bolt you need some padding to stop the bolt without breaking things.
If you don't mind using a sealed magazine there are much simpler designs for loading mechanisms out there.
