This one has probably been asked too many times already, but I would appreciate your comment. Does the use of .38 special rounds in a .357 cause errosion of the end of the chamber? As a kid I was told not to use shorts in a .22 long rifle for this reason. I have been given a heap of .38 spls. and I'm not too sure about using them. They feed well in my rifle if the projectile is seated out to give an overall cartridge length the same as the .357.
