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.
