Kevin - thanks!
I guess I was just asking because...
If I develop my loads at 98F and then go hunting at 32F, I can plug all that data into my software. But, I noticed it doesn't adjust MV according to the temp that I input although it will adjust trajectory according to what you tell it about the air temp/altitude/pressure.
As such, there could easily be another 6" additional drop at 600yds due to 100 fps lower MV.
My point is that you shouldn't assume the software knows anything about the temp stability of your powder.
Hence, you should shoot your rifle in the conditions you will hunt and take copious notes for future reference.
