A friend and I shot out to 940 yards today in fairly strong wind. Bottom line, I would not like to have been the target at 940 yards. I used the Nightforce ballistics program and it was bang-on for my Lapua. We also shot a couple of .308's all the way out to 940 and they hit with nice regularity but they did not have near the smack that the 250 Matchkings delivered. Good fun in the wind and bright sun.
