the down pressure helps, basner, and selby show this in their video's, I have a rifle i'm trying to work up loads and part of the trouble is me .I couldn't keep the crosshair from moving when I dry fired at target. I realized I was gripping the grip instead of pulling straight back. Crosshair moving 1.5 to 3" to right(100yards) griping, no movement with straight back pressure , and also as mentioned above no free recoil or gripping rear bag with left hand.Randy selby ,and Basner recommends bull bag type front rest. This also helped me.
