I am going to start reloading for the revolver I just bought a few weeks ago. I have been reloading 9mm and 45acp for pistols but this will be my first go round with .38 spl. I want to reload wadcutters and several people have suggested Missouri bullets for wadcutters. They have some double ended wadcutters (lead) for both .357 diameter and .358 diameter. My revolver is a Ruger Security Six (6" barrell). So, I don't know if I need .357 or .358 diameter.
I called Ruger and they were no help at all. The basically told me they don't advise using reloaded ammo. I asked them what size barrel it had and the rep said "I don't know"
