My son-in-law got rid of his .357s and gave me 100 Winchester cases that he had sized, belled and primed. The problem is he does not remember whether he used magnum or regular primers. I want to load them for practice loads with 148 gr HBWC and 2.8 grs of Bullseye. Should it matter about the primer used? Thanks in advance for your opinions.
