Ok everyone I'm going I do a seating depth test I'm going to load 5 rounds the same starting at 2.800 and up. What increments should I go up in. At 2.830 I had horrific groups....

Goobie270,
On two of my rifle I had to go over .100" from the lands to get the best group. I made large jumps (.025") and then narrowed it from there.
