As a non glasses wearer I was wondering if most people who wear glasses do so when shooting?
I only ask because I was checking zero with a friend the other day and his rifle was grouping very badly. After a few groups he asked if I'd try his rifle. The diopter was way out for me so I adjusted, shot and grouped well..
Mumbling my apologies I passed his rifle back, he adjusted the diopter to suit himself and shot a 3 round single hole. Much better than the inch and a half groups that he'd put on paper earlier.
I noticed once he'd set the scope to suit his eye the eyepiece was backed out almost all the way to its stop.
Obviously setting up diopter correctly is of huge importance, would wearing his glasses while shooting create a more complicated process of setting up his scope or would it put less strain on his eye and potentially allow for a more parallax free setup?
Oh and all action/scope bolts were checked, no obstructions in stock to barrel. It was purely a wandering zero due to parallax shift
