Well the .02 jump I came up with from reading the instructions that came with the OAL gauge. The instructions said from .01-.03 jump, so I figured I'd start in the middle until I get more comfortable with loading then gradually get closer to find that sweet spot.
Just mainly trying to be as safe as possible. With my daughters ammo I have been loading to 2.232 (.223). When I used the OAL gauge, touching the lands was 2.285. As you can see I was way off. I figure I can at least start at 2.265 as a good starting point.
