I helped a friend cut his teeth on long range he made his first ever 800m shot and connected several other shots with his 6.5 creedmoor AR-10 despite windy conditions that were pretty tricky shooting across this canyon winds were SSW 18 mph with 30 mph gusts from the west. We were shooting at a 30” X 18” IPSC torso steel target. I did pretty well with my 6.5 Grendel AR-15 landing my cold bore shot only missing 3 shots from a total of 38 rounds fired.
