I will start
I have found it hard to practice on a proper aiming point. I have tried various aiming points.
Aiming at the bulls eye I find to be hard, it is hard to see accurately where one is aiming and
it is hard to see if the sight picture changes slightly.
I tried aiming at the bottom of the black, but the front sight tends to bend the view a little
making it hard to aim at the same point.
So I found that one needs to sight at a point a little under the black.
To practice getting used to aiming at the same point and to get used to "seeing" the 10
I practise on targets where I have drawn a solid black line where I am supposed to aim at.
