Shooting from a bench does give max recoil to an immoveble object for sure...plus, any other way you shoot it after getting off the bench will have a different POI anyway...ie: like shooting from a treestand or sitting in a ground blind.
I started something different a few years ago which has had positive results all the way around for me...I shoot from a small chair like they use in a kindergarten class...it's shocking how stable it is, resting an elbow down on your chest, etc.
It simulates treestand / ground blind seated shooting positions perfectly, and lets me adjust the sights and practice for real life shooting positions under exactly those kinds of conditions.
PLUS...as you know, you give & roll with recoil when seated upright, compared to being hunched over on a bench...you can shoot hunting loads "all day" if you want to.
