Hi Jim
If your still getting poor groups and its not the wind, and you have cleaned the barrel, try the single shot tray to see if it improves the groups. If the magazine is aligned badly it will shave the pellets as they enter the breech. I have a friend who uses a rowan single shot tray for FT and he swears it is far more accurate than with the mag. A new board or software update will not improve accuracy or grouping.
regards
Brian
