I assume we're talking .308Win here?

If so, that load is likely too low. QuickLoad thinks it only about 68% fill on default capacity, which is usually low, so the actual % would be lower yet.

QuickLoad thinks that load generates 19kpsi and a muzzle velocity of just 841fps. The bullet is actually slowing down past about 9" in the barrel.

13.0gr should get you around 1,100fps, 12.0 would be around 1,000.

The problem, as you so eloquently put it, is choice.
