Re: Does anyone still make a good 1 inch scope?
For the #1 staying with a 1 inch tube is a good idea since you may need to buy the offset rings that Ruger sells in order to mount the scope back far enough. They only come in 1 inch.
Longest eye relief is the thing to look for here. The Ziess 3x9 by 40 has 4 inches, which is probably the min you would want without getting these rings.
The other thing to watch for is how much the eye relief changes through the magnification range, which is why I wouldn't get a Leupold in the 6-20 mag. 3-14 would be okay.
I don't have a Ziess to know if it changes too much.
