[QUOTE="Ol' Red, post: 2726891, member: 107965"] Last weekend I was testing some H380 ball powder in a .308. I was increasing .5 grain between loads. Velocity increase was fairly even, but did have a jump at about the mid-point. Temperature was in the high teens, so I want to duplicate those loads and retest in warmer temps. My spike was not like your Staball between 56 gr and 57.5 gr. I think you are on track to with your suggested start point to start tuning for accuracy. [/QUOTE]
