180 Grain Sierra Matchking In .308 1 In 10" Or 1 In 12" Twist?

Shooting the Sierra 180 Grain Matchking in .308 caliber, which would provide the most inherent accuracy, a 1 in 10" twist, or a 1 in 12" twist? Both should stabilize it just fine, but I wondered if one would be preferable to the other? The 1 in 10" twist is a 24" barrel, the 1 in 12" twist is a 30" barrel. Bill T.

The 1-10 should be better for your setup.
