I have a Weatherby Vanguard Series 2 in .25-06 with a Leupold VX-III 4.5-14 on it. Where I hunt deer, it would be very possibly to have a 400 yard shot over a wide open field. So if the conditions were right and I had a steady rest and was comfortable with the shot, would a 200 yard zero allow me to shoot to 400 just by holding over? I know the .25-06 shoots flat for everything under that 200 yd zero. Anyone have experience doing this? Thanks.
