Re: Spotting scope - angled or straight?
Absolutely angled! As J E Custom said, easy to use from any position.
I learned on angled when shooting the M-1 Garand and 1911 A-1 for the Marine Corps in Hawaii in 1963 and came to love it. So much easier on the neck.
I have used the straight when shooting Bullseye and that was the only scope that would fit in my Pistol box, but I much prefer the angled.
But to each his own, and I respect the opinions of my fellow shooters.
