Both the hand press and test tube solutions sound good. The powder is the biggest issue as it takes the longest to do. Priming I already do indoors.
I still find the auto-disk fiddly at times. On the whole it is consistent, but very vulnerable to small changes. It is also not very flexible when it comes to upping charges.
For new loadings, I have to do all the measuring with a scale, dipper and funnel. In colder weather, I also worry about the accuracy of my digital scale. I ended up using the Lee Safety Scale, which actually worked quite well. Not as bad as I remember....!!
So, weighing indoors, then off to charge cases: no problem
