Many an expert rifleman, our very own David E. Petzal included, will tell you that because you cannot hold a rifle perfectly still in the field, you should not squeeze the trigger so that you’re surprised when the rifle goes off, but rather pull it at the precise moment when the crosshairs are where they should be.
Of course, you cannot hold a bow perfectly still either. But with a bow it’s different–even counterintuitive and a little mysterious. With a bow, you should go ahead and let the sight’s pin float around in the vicinity of the bull’s-eye and not worry about it one bit as you slowly squeeze the trigger. As I say in this tip, you wouldn’t think that would tighten your groups. But, like magic, it does. At least, it does for me and for a lot of shooters better than I am. Try it.
