hows it going guys new to the forum. I’ve been trying figure out this OCW load development method. Shooting a 6.5-300wby 142g ABLR with retumbo. Started out with .5gr increments from 74-78.5. Looked like I found the node between 77.5-78. So went back and made fine adjustments from 77.3,77.5,77.7,78.0. Any help would be appreciated. I haven’t played with seating depth yet.
