I'm looking for recomendations for a good quality scope for use on California ground squirrels and potentially doubling over to some F-class or LR benchrest target shooting
These are just my opinions, so like some other things, everyone has one and they all stink.
I would use 2 different scopes for your 2 intended purposes. Why?
For the past several years I have spent a month each year shooting prairie dogs. Don't repeat the mistakes I made. My first PD hunt I took these:
AR with a 3-9 scope on it, Sako 223 with a Leupold 6.5-20 Duplex, and 22-250 with a Leupold 36X scope on it.
The 3-9 is insufficient magnification, the 6.5-20 was good for magnification but the Duplex reticle gave no specific holds for wind once I got past the fine portion into the wider portion of the reticle. The 36x was worthless for finding the dogs I had spotted in an alfalfa field. Field of view too small.
So I started PD hunting seriously. Went with Leupold VX-3 had some 6.5-20 and 8-25 powers, most with varmint hunter reticle. The VH reticle just isn't what I needed. Depending on how hot it is when you shoot and how hot you get your barrel, the 25x may not be useful to you. The windage marks are too wide and the elevation system isn't what I'm looking for.
So now all my PD rifles wear the Vortex Viper HS LR 6-24x50mm scopes that are FFP with XLR reticle. The years I stayed for the full month I shot over 5K dogs each year. So I spend a lot of time looking through glass. I found that a first focal plane scope is a necessity so when you change power, you use the same windage holds. With the heat and mirage I don't see a 36 power scope being reasonable.
The NF 12-42 Bench rest scope is a nice scope, I have 2 of them. But the front objective parallax adjustment will drive you crazy on a PD hunt. Works great for a fixed range target.
I hunt mid May to mid June. Wind is typically 10 mph every day, sometimes more. So I don't have a lot of issues with mirage and barrel heat. I know for a 200 yard shot crosswind with a 20 Practical, my wind drift is 3 MOA. So I just hold on my 3 MOA reticle tick and another dog goes to PD heaven. Here is what it looks like and where I hold.
