Re: Adjustable Cheek Piece?
as i am cheap, i have a removable and adjustable cheekpiece setup that i can put from one rifle to another via the use of a pic rail attached to the side of the stock. i have graduation marks on it so i know where to adjust cheek piece to when i change it from one to another.
i do notice a little change in poi changing from bench to prone, so over the last year i "relearned" myself to more of a behind the rifle type shouldering (discussed on the hide numerous times) even off the bench to help alieviate the difference, with success, and not having to adjust anything. this is a path you may want to give a try.
another way is to mess around alittle and find that sweet spot to make a graduation mark to adjust the cheekpiece to when changing from one position to another for each position that your POI doesn't change.
or just dial the difference in, or constantly hold differently to compensate.
whatever way you choose to go, i'm a bigger fan of not changing anything on the rifle once it's "in" or zeroed. sort of using a constant anchor point using archery equipment. but if you are changing anything to a different position, i'd use the position that you shoot most as the baseline, then any adjustments to be made from there.
there really shouldn't be that much of a change at all if you so make an adjustment to the cheek piece, when i was adjusting the cheekpiece it was a matter of less than 1/4" in height. i actually found myself needing more of a forward or backward adjustment, along with a change in pitch to accomodate comfort, but that was way too much changing around, so the behind the rifle type of shouldering practice paid off in the long run for comfort, eye alignment, and no shift in POI. with some muscle memory, it also transferred over to offhand, kneeling, and sitting positions.
