Chubber when it comes down to cross wind, your guess is as good as any ones. When you have a 10mph. cross wind at the muzzle, it could be 15mph. at 50yds. and 5mph at 100yds. No one can tell you what the wind speed is down range. I went to the range last week with my 50cal. Omega and shot five round. At 200yds. useing Hornady 240gr. xtp's and two 50 gr. Prrodex pellets my group was 12' in diameter. On a calm day this same load and rifle at the same distance will shot a 4" group. On a day when the wind is blowing I keep my shots at 100yds. or less. Good luck hunting and with the wind Oldsnow.
