Thread: Seating depth variance between powders

In my limited experience once I have found the seating depth, I keep it there. As an example my 7RM with 162ELDX likes them at 30thou jump. This worked with IMR4831 and Rel 23 but no matter what seating depth I used it would not shoot with 2217. This is assuming you maintain the same projectile. My experience is limited though so others may elaborate more.
