Somewhere around here I have a picture of primers in 6 spent .44mag cases. They were all shot from the same gun outta the same batch I reloaded using a near max load of H110/W296 under a 240JHP. Only difference was 2 each were shot @ 90+ degrees, 70 degrees and minus 5 degrees. While reading primers is no indication of pressure, it's very obvious by the looks of those primers, that there was a good deal of difference in pressure between the three different temps.
