Thread: Prone LOP

Your sight picture is also affected by how far forward or aft you position the scope in the rings (and by the ring height and your cheekpiece of course).
So, my opinion is that the length of pull is mostly a matter of a comfortable grip for your trigger wrist. As said, prone usually requires a longer LOP than standing. Kneeling ought to be similar to standing and I find sitting is more similar to prone.

For prone specially, the angle of your body to the rifle axis will affect the head and thus required sight location and too. The "straight behind the rifle" position might allow a shorter LOP and more rear located sight, I suppose.

As you know, the way to check for natural sight alignment is to mount the rifle to your shoulder in the position you'd like to shoot from, with eyes closed then open them. That's not to say of course that your pre decided preferred position is going to get the best results on target; you should experiment and see the results. David Tubb advocated using your standard technique as a benchmark (control) and testing to see whether a variation gave higher scores.
