One thing about precision shooting, there are NO absolute rights, only absolute wrongs. As an example, jerking the trigger is an absolute wrong. However, always adjust your shooting to your body, do not try to adjust your body to your shooting. If you adjust your shooting you will shoot naturally and comfortably and with great consistency. If you adjust your body, it will tire and your shooting will got to hell.
When I make suggestions, it is just that, suggestions. If it works for you great, if not keep looking. You WILL find that technique that will work for you and your shooting will be natural and not contrived by using techniques that do not fit your body.
As an example, I place full head pressure on my stock when shooting all positions, standing off hand to prone. I know others that do not use full but only some, and then there are those that barely touch the stock. If it works do it. If it does not find what does.
