I'm in the process of putting together a F-class open gun build and was wanting to gather some thought's on barrel contour selection. I know most run the straight 1.250 but was curious if the Heavy varmint would be something to look at with possibly enough diameter for heat and Maybe a possible benefit with less stress on the action with barrel weight and would the extra weight forward be more of a benefit for balance and tracking. I'm going with the Panda F-class action with this build. Thanks Bill
