RE: BEST VARMINT SCOPE
You may want to check out the Mueller brand scopes. I have talked with several hunters that use the illuminated dot scopes for night hunting predators. I don't have one but will be ordering one in the next week or so. My second choice is a Bushnell elite 3200 4-15X40 with the firefly recticle. The thick crosshairs will help in low light or night calling.
