Got my mkii impact with power plenum shooting 33.5gn neilsens at 965 while trying to tune my rifle a prairie dog poped up at 130 yard. Ran the number through applied ballistics and dialed 3.5 mil in elevation and held .5 for wind. Landed a clean single head shot dropped him where he stood! I cant wait to get this thing really dialed in, I have no doubt this gun has the potential for 200+ yards
