After I was done loading 50 rounds last night the temperature had dropped from 66 degrees to 60 degrees I recalibrated my rcbs chargemaster lite and rechecked some charges were all good I then charged 3 cases one with 40.0 grns the next was 42.0 then 43.2 the temperature was 60 degrees I went out this morning I left the scales on all night the temperature outside was 24 degrees F I calibrated the scales and reweighed the 3 cases and all 3 measured the same at 24 degrees that they did at 60 degrees I left the brass charged and I’m going to check it again tomorrow when it’s supposed to be warmer but it’s good to know that I could load in colder temperatures though if I had to
