Questions regarding the He-111 bombloads

[Avimimus]

Regarding the !doubling! of the H-2's bombload:
Could someone explain this? Is it historical? Why wasn't it changed earlier? Was it actually used operationally and why aren't the lightened bombloads available as an option?

Regarding the H-6:
Did no H-6's carry four bombs externally? What is historical?

It would be nice if these changes were explained - or at the very least announced!

P.S. Is it true that the H-12 could also carry six bombs, but that this wasn't done as this rare variant was needed for the Hs-293?
