Resizing 357 near base

[rockquarry]

I've run into the same problem. Just try a different size die, any brand. May not work every time, but I've had pretty good results with this simple method.

Started using the Lee Factory crimp die, it is carbide and resizes the cartridge as it crimps it. Ingenious, have one coming for the 45 acp, just converted the Dillon 550 to large primer. In case something went wrong, it corrects the problem. Guarantees correct dimensions, Larry
