How is the drop tube locked so it won't move? It is also the wad seater and I want to keep a certain wad pressure so I don't want it gradually shifting up. I put a magic marker line on it for a visual indicator if it should shift but it seems rather bizarre that it doesn't have a lock nut of some sort.
I found a schematic and there is no provision for a lock of any sort that I could find.
Any thoughts?
