Shawn, I know! I remember a 690 muley I killed in MT. First shot kill but afterward I realized I had made two small errors in my ballistics setup. Luckily they offset each other and I got to eat the venison anyway.
By the way, I have always adjusted for elevation, just not other pressure changes.
I'm no weather wizard but the way I understand it is if the Barometer drops so drastically that it effects your shooting, you are probably shooting it a thunderstorm. which most of us arnt shoot/hunting much in anyways. JMO.

I am the way I am because I watched the movies "Red Dawn" and "Tremors" at a impressionable age.
I set my Kestrel to read station pressure. I just returned from a scouting trip. The pressure at home before leaving was 25.49 (5889'). The pressure where we were scouting (11,000') was 20.??. Five inches or more pressure change from where i shoot to where I hunt!
ok, dumb country hick here, don't know if I do it right or not but here's how I do it
I have a casio sea-pthfinder watch which after I press the button in 2 seconds it gives me station pressure (bar pressure where I'm standing) I enter this into exbal and enter zero for the altitude.
My understanding of it is higher altitude lowers the bar pressure, which raises the bullets BC.
this change in the BC is why altitude effects the bullets flight, so if you know your bar pressure, exbal compensates for it and altitude can be left at "0". if you put in a bar pressure reading and an altitude reading it over compensates, Is this correct?
