Thread: 6.5mm 143gr ELD-X first load development

My current seating depth is probably 5+mm from the lands. Seated that long I don't have (imo) enough case grip on the projectile. Will fine seating depth adjustment really affect things that much?


The 46gr load appears to be at an anti-node when looking at the group vertical:



So I guess I'll try something like the following for the next round:

45.7
46.0
46.3
46.6
46.9
47.2

I'm nervous about going too far above 46.5gr as I was starting to get some sticky (but not stuck) bolt lifts.
