In the odds n' ends box I found a
carbide .38 COLT sizer. A pretty exotic sounding die that no doubt cost some loot. However doing some checking the dimensions on a .38 COLT, long or short, are a nominal O.D. of 0.381", where as the .38 Special is 0.379". What's 0.002" between friends?
Now I have not yet tried it out yet, but I am surprised that they even make such a thing.
