[QUOTE="Veteran, post: 2226004, member: 118038"] Yep, I second running your measurements from the OGive on the specific bullets you are using to the lands. Use the Hornady or other tool to zero in on the lands, and measure Ogive to lands to measure your jump. I don't think the data you show between 3.595 and 3.613 is statistically different with so limited a data set. It is indicative like someone said that you are in a node range in that area. You will need to shoot some 5 shot groups and fine tune your powder and more seating depth tuning in that one area to really pin down something that is repeatable time after time. You defined a range, now you need to get to something definitive which is repeatable. The 3.613 data with an ES of 47 may even be just a one time fluke? How do you know? See what you get the next few times through. Over the range, I might trust data with lower ES's, but you got to shoot and fine tune to know. [/QUOTE]
