Playing with a Benjamin Airbow (standard not the M600) with a PARD 008sLRF utilizing a ballistic calculator. Group was shot at 88 yards before finalizing on the BC. The wind picked up soon after and groups were negatively impacted to the point of being unusable at that range for coyotes. Settings corelate to a 55 yard zero and 88 yards using the balistics calculator. Will have to play more to see if those settings correspond accurately to other distances.
