    I checked MRS. QKs S&W J Frame a few years ago and .357 Magnum will not chamber in her Smith.

    IMHO the only way 357 will chamber in 38spl is if the bullet is seated too deep and the OAL is within 38spl lengths

    The rounds may chamber depending on how the cylinder is reamed. Most 38"s should safely handle the pressure, since J/K frame's are commonly chambered in 357, not that I would recommend it at all, I just don't think it would blow up in your face.

    I am surprised they fit in the box.

    It's not the COL, the case length is longer than a .38 for that very reason--so it won't fit in a .38.

    Maximum length on 38spl is 1.550,case length of a 357 magnum is 1.290,so a 357 case will load into a 38spl chamber with a little over 1/4" from the end of the chamber,like I said the bullet would be set back into the case a lot,but you can load a 357 case into a 38 spl chamber

    Without moving the bullet into the case quite a bit they wont chamber. Op was saying factory ammo put in the wrong boxes. Reading that getting a box of 357 labeled 38 the cartridge wouldnt go in the revolver anyway.

    Sorry but for everyone's safety I must challenge you on this. Please look at your dimensions again, you have digits out of place. If an empty .357 Mag. chambers in your .38 special the gun has out of spec. chambers.

    +1. That's the reason .357's shouldn't fit in a .38 revolver. I agree with 40Bob that it shouldn't be a problem, at least in modern .38's. I'd be especially careful if I had an older revolver that was not designed to handle at least +P pressures.

    You folks are putting out speculation that is going to get someone injured.
    SAAMI limits ARE 17,000 PSI for the .38 Spec., 20,000 PSI for the .38 Spec. +P and 35,000 PSI for the .357 Mag....
    Please, DO NOT FIRE .357 Mag. ammo in a firearm designated for .38 Spec. rounds. Common sense will tell you the firearm must be different to carry the additional 15,000 PSI.

    Simple answer is that unless someone has done some very very unusual things to a 38 revolver they will not chamber a 357 mag cartridge. The 357 cartridge is specifically designed NOT to chamber in a 38. Ive never seen one that would I doubt anyone here has either.

    You misunderstand, I did not say it was ok to do so, only that if you somehow put a 357 in and it fit and functioned, a modern 38 special SHOULD not explode in your hand. In no way shape or form did I say it was fine to do so.
