Standard Atmospheric Pressure for Long Range Shooting

I’ve found myself needing to reference this info a lot while making data cards. It indicates the standard atmospheric pressure at different elevations. Pressure can vary quite a bit from the “standard” listed here, and although that won’t make much of a difference at short or mid ranges … when you get out to 1,000 yards or beyond it can make a noticeable difference. If you know the specific pressure the day you are shooting, it could really help your ballistics tables be more accurate. Having a Kestrel that can measure the instantaneous pressure is the best solution. Altitude (ft) ...
