Just a firm grip that holds the butt in the shoulder and the stock down on the bag . You don't want the gun moving back too much as it just upsets the rear bag and teh bi-pod feet can dig in . Also if using a Harris bi-pod leg notch model make sure you do not have the feet sitting on the springs at the lowest position . This can cause high shots . Come up into the first notch and adjust the rear bag . Experiment a bit with the pressure of the grip and see what works best.
You will not get any reassurance with a 5 shot group if you are blowing the group with the 4th or fifth shot all the time .
Firing only three tests the rifle and load , firing 5 test you.
If you start with three shot groups it cuts out a lot of variables helping you get some consistency and tune a load then when you can consistently get a tight three shot move to firing more shots in a group .
Look I see Military and Police trained snipers that are not controlling recoil well at times . Stock design has a lot to do with it . Light guns are a pain .
If you move to the dirt make sure you load the bi-pod before each shot and don't put the bi-pod feet down on lumpy rocky spots .
