On clothing.
My summer length of pull is 16.5" this is a pain in the forehead, with scopes and standard stocks anyway, but with peep sights, it's a blessing. I get nice and close.
I do get smacked in the nose by my own thumb at times however.
In winter, my length of pull is shrunk by clothing for me, that means the scope now doesn't hit me, and taking the apperature out of the peep sight to maintain field of view.
I have one custom stock so far. Problem is, it fits great in summer, too long in winter.
Solution? nope.
Work arounds yes, you get used to it.
My next custom will have a 15.5" pull length, a comprimise for both seasons.
