They don not even list it in the annual for 243???
Cyberguy, two things come to mind.
They haven't gotten there yet, a fair possibility.
The expansion ratio for the .308 is nothing like the .260. A more likely bet. It seems as new powders are developed, they are for narrower and narrower applications. Powders suitable for the .243 (6mm-08), are useful in the .260 (6.5mm-08), but rarely tops in a 7mm-08. By the time you hit the .308, the requirements are quite different.
