My discussions with the Ballistician from ADI is that your belief may be in your own mind. Their powders exibit the same temperture stability across the range of powders and that's what they were designed to do. Other factors at play here I would believe if that's the result you experience over all.

In TAS powder supply gets a bit erratic at times and I like continuity of batch so I don't have to check velocity too often, I never run lower than 1kg of powder and buy as soon as I reach that point(not as often now). Here last year I reckon I was the only one in the north part of the state with any 2208 left, only due to the fact I bought a heap cheap when a local gunshop shut down.
If you are running a good load you want it to stay consistant as long as possible and I personally believe that there are minor variations batch to batch, all loads from a new batch of powder should be checked from a safety and accuracy point of view.
