I need some guidance on seating depth. I measured my 7mm Mag using an OAL guage and I got 2.76 inches as the point where the lands meet the ogive.
My plan is to try a few different setback distances to see which is the most accurate.
I began by seating my bullets to 2.754. I loaded 30 rounds with this seating depth using 3 different charges of H1000.
I'm going to load another batch and my initial thought was to seat the next group to 2.75. This is just an arbitrary number though...so I thought I might get some THR wisdom on this matter.
I'm not experienced enough to know if changing from 2.754 to 2.75 would make a material difference or not.
What are your thoughts? At what depth should I seat batch number 2 to get the best information out of my next shooting session.
