The 357 has a very long case. I would think you could mold a very long boolit and still have room for a powder charge and stay within overall length requirements. What is the maximum weight possible or has been tried. Imagine a 250 grain doing 700 fps instead of 125 grain at 1400.
For most revolver uses at less than 15 yards bullet drop is not an issue. Just wondering what has been tried and even if really heavy makes sense.
Heck even if it tumbles it might make a heck of a wound channel. Thanks for any experienced input.
