Use the smallest aperture though which the target still seems bright enough to see - fine apertures work best but darken the sight picture. If none of the above works, maybe it is time for a No.4 (T)...
I did notice an improvement when using the smaller aperture in the ladder sight. A No.4 (T) probably isn't in my future, but I do have a no drill mount which came with my No. 5 MK1. Might have to try that.
