Might try using a larger aperture in the front sight globe, you'll still naturally center the bull, but when blown off its easier to tell by how much. Its almost like a spring loaded thing for self correcting, rather than the "on-off" feel you get w/ a tight aperture, you will know by how much you are drifting. Try bigger peeps in calm condition until you find your "groups" opening up unacceptably, then run a touch smaller. As long as your scores improve in the wind it doesn't really matter how much worse your theoretical accuracy suffers. HTH
