In regard to patterning I admit to not doing it regularly even though I’ve often read about it even back in my youth (Bob Brister?). The exception being the different turkey loads. I’m a snap-shooter on pheasants, kind of like the instinctive shooter with traditional archery, and grew up with no formal mentoring or training.

If one is consistently and exasperatingly missing and goes through all the aspects of shooting — stance, eye-dominance, gun-fit, cheek-weld, choke use — in an attempt to sort out the problem, it makes sense then to me to pattern that gun with the appropriate loads also.
