RE: TARGET AND VARMINT RIFLE
 

Nice choice on Rifle and caliber.

If you go with the 20X, remember, any slight shaking or movement on your part willbe noticedwhen looking down range at full 20X power.

I like the 4.5X14 better for field applications. The 6.5X20 has more critical eye relief and the mirage effect is lot worse at the higher magnification end. Might be a little better target scope, but for the combo I would pick the 4.5X14
