    A friend of mine has a H & R "break back" revolver calibered in 38 S&W. We already know the "break back" is a major safety concern so we would like to test it with a reload rather than commercial loads. We would prefer not to invest too much if anything in brass and dies so we concidered cuting down a 38 special case, since I already have the brass and dies. We know the 38 S&W is slightly larger in Dia. than the 38 Spl.
    That is why we would like to draw info from more experienced hand loaders on this project.

    If you're not sure about the integrity of the firearm, take it to a gunsmith or call it a decoration piece. Do NOT fire it.
    Learning if your $200 antique handgun works is not a reasonable trade-off for risking your hands, face, etc.

    It would be certainly be fired from a vise NOT by hand. Gunsmith? I dont have any locally I would trust.

    Here's your problem. If you cut 38 Special brass down to 38 S&W length, your Special seating die's crimp shoulder will not be low enough to crimp it.

    Do you, by chance, also have 9mm dies? If so, you can crimp it with a 9mm seating die. 380 will work, for that matter.

    A cut-down 38 special case will work in a 38 S&W chamber. Your case life will be short, as there will be much expansion when fired, and then resizing too small, giving you, again, much expansion when fired. I doubt you'd get more than two - maybe three loadings out of it before you got cracks.

    Thanks for the info.
    I do have 9mm dies I could crimp with. I'm not too concerned with reload cycles.
