.357 or .358 diameter?

    I am going to start reloading for the revolver I just bought a few weeks ago (Ruger Security Six, 6# barrel). 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. 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"

    Well, Missouri Bullets has .358 diameters but theirs are not hollow base. Precision Delta has .357 diameter and theirs are hollow base. I would prefer to use the hollow base, so will .357 be OK?

    Ideally you should slug the barrel to find out the actual bore.

    With a hollow base you would probably be ok.

    .358 for cast or plated is the general rule .357 for jacketed.

    I thought a binomial question was asked of me. My answer still stands.

    Like said above, usually .357" for jacketed bullets and .358" for lead bullets. It's a good general rule.

    well that explains the weird look at the LGS when i asked for some .358 projectiles and was asked if i ordered them in... then he had to fish around out the back for a box. (psst $48 for a box of Hornady 158gr HP/XTP... fmd!).

    i didnt know the jacketed vs cast difference. :)
