Hello!
Yes, our modern law after some gun rampage at school in the last years in Germany, the possibilities for sport-riflemen/women are very restrictive. I think, you cannot imagine in US (the country with free-arm-ownership) what we have for difficulties with it. There are a lot of political parties, who want to ban the sporting arms completely. And I think, the difficulties by law are the barrier, to spoil the party...
The lawyers guidelines for reloading at home are like this, that you are not allowed to load in a room, where you sleep, live or work. It has to be a separate room like a hobby cellar. There must be a plain floor cover, no carpet. You have to store your powder in the plastic bottle in a wooden box (lockable), built without metal-elements, no screws - in eventuality of explosion, that there are no metal parts flying around. You get only a prescribed lot of powder per year. If you need more than 1 Kilogramm per year, you have to submit a request to the authority. And so on. Yada-yada-yada!
You see, it is not really funny...
...but we can live with it. It would be nowadays horrible, if everybody could buy so much powder like he wants to make nonsense with it.
