So I'm doing the dummy round process with my new 260R barrel and it seems one of the lands extends further than the other 5. I'm trying to achieve the mythical .010-.015" jump associated with ELD bullets using the sharpie technique but I'm down to 2.76" and there is still one land that is barely touching the ogive.

Should I use this as the basis for the jump or where all 6 lands are touching?
