I know this thread is old, but I am listening to the podcasts trying to catch up. I think my biggest inconsistency in my form right now is how hard I pull the rifle into my shoulder with the right hand. I've experimented and found that, group wise, I seem to shoot the best when I don't put any pressure back into the stock grip with the bottom 3 fingers on the shooting hand. If I load the bipod and rifle into my shoulder, then pull backward on the trigger (2.5 lbs) while just resting bottom three fingers on the grip, I get better groups. I 'm pretty sure this is wrong (pulling whole rifle into the shoulder with the trigger can cause aiming problems) but I did it to isolate that its my rearward grip pressure that sometimes hurts me. I also think it could be affecting my muzzle velocities as I struggle to get great ES numbers no matter what I do with the ammo.
Any suggestions from anyone on how to achieve the same rearward pressure into the shoulder with each shot? How much pressure should there be?
