For Varmints and Targets Leupold 8.5x25LRT. Fordeer hunting and a Varmint set up Leupold 4.5x14LRT. The LRT gives you elevation and windage knobs. You probably won't need to bother with the elevation knobs deer hunting with a new shooter but as time goes on and the distance increases you may want them. Varmints over 300 yards you will like the elevation knobs. Out to 500 yards they are a must. That 25-06 is going to have about 41 inches of drop in 500 yards with a 100 grain bullet. Dial in 33 clicks of elevation and bang you're in there. Hold over is a guessing gameat that distance. There are other scope options out there these are just 2 of my favorites and what I use.
