I recall you bringing this up years ago in same subject post.
I see the issue is more Relative Humidity than temperature ?


I am who I am - I am not who you want me to be.
Therefore I am me.

There are two pages, the other being temperature and pressure

While there are effects of relative humidity. One must bear in mind where you live and where you will be doing load development and hunting. In some places there is generally a narrow range of relative humidity, and others, quite a wide range. As an example, in George, there are crazy extremes: when the mist rolls in from the sea and it rains all day, its normally around 80-90%, and when the berg wind blows from the other side, it can drop as low 30%. Now if you hunt on the highveld in winter, the range of RH is quite small, and thus negligible. However, the extremes of temperature are more relevant, up to 20 degree difference between early morning and mid day temperatures. Granted, the RH will cycle as it heats up and cools down, as the two are connected.

RH will only be of relevance during reloading and exposure of the propellant for long periods. Once the round has been sealed off by the bullet then only temperature will have an effect.

^ This. Cartridges are hermetically sealed when properly assembled.
