I've run 125-180s, of various Nosler and Sierra types, for 30 years. The partitions, BTs, and SGKs have always worked....just intrigued to experiment with my 30s and the same new bullet advantages being given to the 6 and 6.5 stuff. There's plenty of tried and true hunting bullets in 30, but some of these new pills do all that AND hold velocity/energy past 500, and drop and drift less, if one is inclined to practice out there....even 180 NPs can't compete with BC
