We do not manufacture a Lee Loader or Lee Load-All in 410 gauge, since it is very difficult to reload and the availability of reloading components is sparse. There are also some obstacles in tool design, like very small drop tubes, that prevent the free flow of shot with frequent bridging. We do not have any plans in producing a tool to reload with .410.
We suggest visiting our neighbors to the North at MEC (Mayville Engineering Company)
