A simple question for any professionals who may have once done some training down under. Does anyone herebout’s with LE, or active duty military service under their belt, have any experience, or history with the South Australian Police, and if so can you answer definitively as to exactly what caliber they were running through their S&W M66 .357’s prior to the change over to semi-auto M&P’s, was it .38 spl or .357 magnum? Bonus points if you can ante up the exact loading? 
Nobody out there knows?
Winchester Western 38 Special 158 grain lead round nose.
Can you offer more substantial details then that?
