I am loading for my Remington 308 700 I full lenght sized them and neck sized them and did not notice this the first time . All trimmed to 2.005 Shot them and they shot just over .58 at 100 yards So I go to load more tumble them then just go to neck size them . Loaded round measures .331 using a redding bushing .327 Am I just neck sizing to much to cause this bulge ? Right above the shoulder I believe I have the neck die set up correctly , I neck size for my 300 ultra and my 7mm-08 with redding dies also with no problems ? Is it me or do I have a die problem or is.004 to much to neck size this brass ? Help here is a pic of the brass .
