Aim small miss small. I use a half inch white dot (white target patch) in the center of my black bulls eye ten ring. It makes it easier for me to see when the reticle (cross hairs) are nearly exactly centered on target. Hard to see a half inch dot at lower magnification.
I also adjust my scope by taking up the same sight picture I shot from the rest and talk a friend into moving my cross hairs to the bullet hole (s). Hard to see a bullet hole at lower magnification. Then I fine tune. My way seems to save a lot of wasted ammo.
