Yep, done that since I started reloading .38 back in the 80's. Theres a theory that if you use .38 special in a .357 chamber for any length of time, that extra 1/10 inch gets filled up with lead and crud.... so when you do want to chamber a .357 it won't fit.

If you always use .357 brass, it won't be a problem..
