Hodgdon I’ve seen roughly a half fps to degree in increase heat that bell curves at the extremes 90 plus and below 30.

It won’t change your load that much but bring a portable fan to keep you cool so you can still shoot in the summer some

ah yes a fan . my fan is a air mattress pump with a hose end that is put into the chamber . it does speed thing up

Depending on how far and what kind of shooting you are doing, you will want to learn to keep track of the temperature and Density Altitude as well.

Internal ballistics and external ballistics are often separated in classrooms or forum discussions, but in the real world Mother Nature demands her dues.

Keeping track of the stuff it takes to get hits regardless of the temps and weather isn't for everyone, but to graduate to advanced shooting and tuning, it is a requirement for the kind of shooting where there are no sighters. YMMV
