As far as humidity goes. I keep my gun room at 30% at 70 degrees, (44.5 dew point) and sometimes it the middle of the summer with the AC going and all the dehumidifiers going it gets as high as 35% or 47.6 dew point.
When I load, I seat the bullets shortly after the powder is poured. The powder measure is covered/sealed so the powder does not gain or lose moisture. I won’t allow the powder to be exposed to the atmosphere any longer than necessary.
As far as sd and accuracy goes, I use three five-shot groups and average them. (True if I get one flier in one group I’ll reshoot that group. Maybe that’s a mistake??? I’ve always blamed the guy pulling the trigger-me.)
This isn’t perfect, but that’s been my practice. I wonder now if I should keep that flyer group in the average? If two group have flyers, I alter the load to get a more accurate or better load.
