[QUOTE="AZShooter, post: 1351397, member: 5219"] As long as this old thread is alive again...I must say it is interesting and worthy of saving in my documents file. The manufacturers of these powders have interesting phrases to describe the powder's insensitivity to temperature changes. I have to wonder about the accuracy of IMR 8208 BR as .59 per degree. It is billed as being "virtually no change in velocity at temperatures ranging from -40 degrees F to 165+ degrees F". I would think it would be similar to the low number of Varget. Hodgdon also says Varget "is insensitive to hot and cold temperatures" and Backwoods83's list says .19 per degrees, the lowest on this chart. Tim: RL-17 (alliant: "Consistent maximum velocity in extreme weather conditions") has same makeup as RL-33 ("Its double base gives it consistent performance across temperature and humidity extremes") and RL-26 ("Controlled temperature stability") but the report has RL-17 at 1.42 per degree. You said RL-33 is .58 per degree which has it as one of the powders with the least change. Wonder what RL-26 will actually show? [/QUOTE]
