hi, i have found a good load of 67.3 gr h1000 for my 7 rem mag using my brand new unfired nosler brass. getting decent es and sd and good groups. however, after firing, the shoulders have reappeared about 20 thousands higher on the case, obviously creating larger case capacity. is that increased case capacity going to make any significant difference when i go to reload the fire formed cases? as far as MV? do i have to "find the node" again, so to speak, or can i just happily use my same load and expect same results with perhaps even better es/sd since the cases are fireformed?
