This might look like a stupid question and not sure if it is the norm. How much do you adjust loads from summer to winter? Or do you stick with a single load and deal with the velocity loss or gain by simply adjusting your scope accordingly?
A lot of that depends on the powder you choose, and how sensitive it is to temperature. All I do is try to stick with Hodgdon "Extreme" powders, and not worry about it. That, and ignore drop data from times when it's anomalously hot.
