Around a big field or out on the plains, it might be calm or just a slight breeze where you’re sitting and glassing, but the wind might be blowing a near gale out where a buck is walking or feeding 200 to 350 yards away.

“Glass the leaves or weeds around a deer, whatever you can, to determine if you need to factor in the wind on your shot,” says Texas rifle maker and crack game shot Lex Webernick.

But don’t worry about remembering some fancy wind-doping equation. “If the wind is blowing 5 or 10 mph and the grass or weeds are moving slightly, hold dead-on a deer,” says Lex. “But if you’re having trouble keeping the cap on your head, you’d better hold a little bit into a crosswind on a deer on shots farther than 150 yards.”
