Quickload Temperature input question

Good morning I just bought the latest version of the software Quickload a month ago and I been having a lot of fun....

I have a question about the temperature input

How do you supposed to enter the temperature on software
Do you get the actual ambient temperature??
OR
Do you get the temperature from the cartridge itself (with laser gun temperature?????)

I say this because you could be shooting outside and have the ammo inside a box under a shade this could be a big difference in temperature
100 F ambient and ammo will be from the box 80 F

I have seen a few different people on YouTube that take temperature from the cartridge meaning that's the closest way to get the temperature of the actual powder? maybe?

All what I want to know is what is the right one to enter on Quickload ....Ambient temp or cartridge temp ???

Thanks
 
If you hover the cursor over the thermometer symbol, a yellow text box will pop up that tells you to enter the powder granule temperature.

It is ambient temperature. The assumption is that you developed the load with whatever barrel temperatures your shooting pace tends to generate and for however long you let the rounds soak in the chamber at your rate of fire, and you will use feedback from your results to get the programs output to match your results. That, or you will note the error differences and use them adjust your predictions. The ambient temperature will then create a temperature offset relative to those conditions, allowing it to compensate.

Note that there are now an ever increasing number of temperature stabilized powders for which that temperature change setting will not work. You can, however, work out a correction factor by experience. That is, if the temperature compensation predicts a change of 30 fps, but the actual change is 15 fps, then you know that powder wants you to put in a temperature change that is only about half as many degrees as the actual change in order to give the right result.

ambient? is nothing more than the surrounding temperature. Ambient is not as sinister a latent, latent means hidden. Shooters loading for the winter hunt could store their ammo in the freezer and take the ammo to the range in coolers.

There was this story about men paying big buck to go ice fishing. About the time their time ran out they found a young fisherman that was catching everthing so they ask him what his secret was. They could not understand him, just before they got upset/angry at him he spit out his worms and instructed them to keep their worms warm. He could have warmed up a few bricks and used them in a cooler but if he was anything like me when I go somewhere I have more than I can carry.

Good story. Just think of your stick powder grains like little worms (but don't put them in your mouth).

Denton Bramwell uses the cooler trick to do some temperature sensitivity testing in this article.
