That's quite an interesting string there. None of the ballistic programs that I know of have even considered entering Barrel Temp. Just look at the repeating variation in that string!
They could be letting you enter a cold MV, and then a few more at set times to establish a curve. I'm surprised that such an important constant is missing off Applied Ballistics (I know they have
powder temp which may be the same basic thing). I reckon a 'comp mode' that uses the phones bump sensor to register each shot...

So Brian Litz if you're listening, be a good chap and add that in for us ....
*I actually just fired that question at him. I genuinely reckon that be a good thing to add

One of my clients who really has his shit together with shooting LR & ELR, keeps a very close eye on barrel temp, amongst other things.

Just curious, with barrel temp, projectile/powder temp, etc.... which are outside the apps calls, does your client aim for a certain value or actually 'dial' on variation?
