I got to thinking about this the other day. I use density altitude based range cards 3 different columns for ammo temperature. My range has covered shooting shacks so they're always shady and a lil cooler than out in the sun. I measure the density altitude by leaving my Kestrel out in the sun for a few minutes, my logic being that the conditions that will affect the external ballistics are out in the sun and measure the temp in the shooting shack as I figure that the temperature of the ammo is what affects the internal ballistics/muzzle velocity? Does that make sense? Anybody do this differently? Could I be getting erroneously high readings if the Kestrel sits in the sun too long?

Where do you measure atmospherics with your Kestrel?

Dont let the kestrel sit in the sun and use that for a temp reading. It will get real hot real quick. Mines OD and gets 45°C some times.
Pretty easy to test for youself tho.
Swing your kestrel around on the end of its string if it sits in the sun to quickly cool it off.

As Kona mentioned.
Don't leave it in the sun. Temperature is actually measured by heating an element and measuring resistance. It should have a slight breeze to be more accurate.
Your bullet travels through air temperature, not radiated temperature from the sun. Being out in the sun will definitely give you incorrect readings and not representative of air temperature.
