Re: Your opinions on 7STW Scope
That Leupold VX-3 is what I placed on my 30.06 last year. It has the Boone & Crockett rectile - for the 30.06, I couldn't be happier. I performed some low light range tests comparing the older VX-II with a 50mm objective. The new glass in the VX-3 scope had noticeable improved light gathering abilities when compared to the older, larger objective Leupold.
For the 7STW I am thinking of a fine crosshair, but do not want the crosshair to break while shooting that cannon - recoil.
Long distance shots will require a non cluttered and fine wire crosshair.
I was impressed with the light gathering abilities of the VX-3 40mm Objective. It left me wondering what would a larger objective could gain...and what would the drawbacks be.
