I chronoed consistently 131-132pf on my chrono last year. Using same 8lb jug of powder on every load. Shot matches from Charleston,SC to Barry, IL and ranged from 126.4-137pf. So many variables play part in the chrono of ammo. I stay atleast 6pf over forbthe just incase. I would hate to drive 4hrs or more to a Level 2 and not make pf. Seen a few friends make that trip and it sucks!
