Rawson sight usage
May be someone can help me.
I just had a Rawson aperture sight installed on my N°1MkIII SMLE. The piece is complete with all screws, plates etc and fits perfectly on my rifle.
I have some problem in understanding the elevation scales. I know that once on target it would be just an adjusting a click or two business regardless what the scale reading is; nevertheless I would like to understand how these readings works (e.g. for quick range adjustment for longer distances).
These scales reminds me of a vernier gauge but I am not sure how to read them.
Thanks for your help
