You are totally allowed to store ammo at your house.
The ones that you get when you go do your mandatory shooting rehearsal have to be completly expanded but you can just buy a case and bring it back home.
With some friends we were going to the shooting range quite a lot and bought like 1000 rounds and stored them at one of my friend's place to take advantage of a bulk discount.
I was talking specifically about the issued military arms and ammunition in that comment, which is what the comment I responded to was about. I made a separate comment later about privately owned arms and ammunition but I could have been a lot clearer. Botched in the edit.
