I loaded up some 357MAG rounds and fired 24 and found that the primers are all flat and cratered. What did I do wrong?
I used the #6 Nosler reloading starting load for their 158gr JHPs. I followed everything that they recommended. Federal 357MAG brass once fired by me. Winchester's small pistol magnum primers and 15gr of H110. I trimmed the brass to 1.280 and gave a tight crimp. The COAL ran between 1.579 and 1.580.
I first thought that my scale was off, but I have checked this against another scale and they both are within a tenth of a grain. I fired these rounds in my GP100.
Any help would be appreciated.
