I do know how to focus the eye piece on a scope.
my question is ...... every time I am at a gunshow and an “older guy” picks up any given scope, the very first thing many do is back the eye piece wayyyyyyyyy OUT and then focus the reticle. I usually reset all used scopes I pick up by first recentering the crosshairs on a mirror, then turn the eye piece all the way IN and then back it back out until reticle is focused.
These “old guys” must know something I do not. Does it possiblly add a bit of magnification? Does it extend eye relief? What in the blazing hell is the reason these guys do this? I could test it myself, but its cold, crappy and I am too lazy. Hoping someone here has an answer before I try this. I always forget when at the range.
