Tom,
You've already used TAC some, and it's just as temp-resistant as Varget or any of the other Hodgdon Extremes.
It's been reasonably available both in stores and on the Internet for most of this year. You've just got to be quick on the draw. If you keep checking websites you can pick up an 8-pounder for less per pound than it can be purchased in stores, even with the hazmat fee.
