The E-Tips can take some work. In my 25-06 with RL26, I did a ladder test to find an accuracy node and then it still took several groups to find the right seating depth. Started at about .065" off the lands, that was shooting over a 2" group at 100, but I continued shorten them until I was .115" off. That depth continues to give me under 1/2 moa, the best was a .32" group. Don't give up.
