it literally is the same capacity and bullets. You can manufacture unique bullets by allocating a LEE .401 push through sizer and after lightly lubing, forcing .410" .41 magnum projectiles through it, on a SINGLE STAGE press. I've done hundreds for 10mm and .38-40 applications.

.41 Special data is also useful. Generally you can begin with 10mm auto data and work from there. The greater capacity will ensure slightly reduced pressures. Keep in mind listed precautions reducing slow burning powders in relation to case capacities.

The .400 is great caliber and fun with a little imagination. I can shoot 135 - 230 gr. for special applications.

I was trying to replicate ancient shot loads, still working at it.
