If you have it, you are better off using 'Call down the thunder' to aggro and then you won't waste any ammo (and you get +1 IP too).
Twitch hunting is really the only way to stop this problem. Another thing you can do to help is disengaging (using the sword/olive branch icon in the top right) from combat as soon as it flees. That way it will stop running after a short distance and you can aim another shot.
