[QUOTE="dsculley, post: 1260391, member: 77514"] That would be an acceptable method. Where you get into trouble is testing in cold weather, working up a load near published max and then shooting that load in much warmer weather. Your method will work based on what you described. I would probably put the rounds in a small cooler when I left the house. I would have about 4-6 fouling rounds to get the chamber up to temp, then test. You might consider letting the rounds sit in the heated chamber for a minute or so as well. Common sense goes a long way in this hobby. Sounds like you have a good dose of it and are trying to apply sound reasoning. Even though H1000 is considered to be temp stable, that is a large temp swing (40° C or 73° F) so you can probably expect some difference in pressure/MV going from one extreme to the other. The only way you will know is to test at each extreme, however you should be able to get a satisfactory hunting load with the method you described. [/QUOTE]
