Is there a consensus on what the "perfect" calling/walking varmint rig might be? In other words, if you were to put one together, what would yours look like? Or, is there a factory rifle that would be your idea of "perfect"?

I know a lot of guys use standard sporters in varmint calibers for calling/walking varmint rigs. I'm thinking I'd like mine to have a bit heavier (but not varmint weight) barrel for a bit more stability when shooting off sticks or a bi-pod.

What do you guys think? If you have the perfect rifle, how about some pics!
