I have a Weaver K-10 scope which I acquired from Ebay several years ago. Functions well on my Savage 340 (22 Hornet).
Enlighten me....the reticle (fine cross-hair) position, as viewed through the sight lens, changes as adjustments for windage/elevation are made....approximate age of this scope?
I recall that many years ago scope ads underlined that their reticles remained centered through the sight lens.
When did the technology in internal adjustment scopes in which the reticle remained centered become commonplace?
Did sniper scopes of WWI & II have this feature?
