[QUOTE="nheninge, post: 477432, member: 13085"] 100 fps difference over time could likely be chronograph error et al. Were conditions exactly the same over time? I also believe that an ambient gun temp with cold powder does not tell you much. So these "freezer tests" on powder are basically worthless. Actually shooting in cold air vs. cold round, warm gun is NOT the same. The starting temp of the powder does not matter much when it is heating to several thousand degrees. Temp effects on shooting are MUCH more than just a frozen cartridge. Granted you are just evaluating powder, but IMHO the only real way to test this is by actually shooting in different temperatures. This is no different than evaluating your rifles drop at different station pressures. [/QUOTE]
