One turn will change a different amount based on distance to target. Also depends on what brand the sight is. My experience is one turn will change your POI but not significantly unless you are competitive target shooting. A deer at 30 yrds probably wouldn't notice much change at all.
I'm sorry that I can't give you a more specific answer. It's been a while since I have sighted my peeps in. I've been doing it long enough (4 peeps) that when adjustments were needed I just dialed in some guesstimate Kentucky windage and it usually got close enough that only a slight tweak was needed. I honestly can't convert KW and tweaks into clicks
I would suggest using a solid rest and shoot a 3 shot group. If possible to lock your rifle in the rest, I would put the sight on the bull and adjust sights to the group. hope this helps.
You can measure the threads on the adjuster and make the other measurements of the sights to have an accurate way of determining what one turn will do. If it has fourty threads per inch it will move the sight .025” and then knowing the distance between it and the front sight you can calculate the impact change at any distance.
