When I started ten years ago, my 'sponsor' went shopping with me....
I would pick out what I wanted, with a lot of guidance from him, and I would pay for it, but he would keep it for me...both restricted and non-restricted.
We would meet up at the club, and he would bring 'my' firearms. I would shoot them, and he would them take them home...
When my PAL and club ATT came through, he simply transferred them all to me and I took them home.
Easy peasy...no waiting...
Of course, not everyone knows of someone whom they either trust enough, or is willing to do it.
