The 38 special developed out of the heeled .38 Long Colt cartridge, the .38 S&W is a totally diferent cartridge family. Turned out the old 1890's .38 LC Army and Navy revolvers took a heeled .375 bullet. When the Moro tribesmen didn't realise they were being shot, S&W lengthened the .38 Colt so the shorter soft .38 LC could be shot for practice through their newer .38 Special non heeled guns, or so I have read. The army just brought back the peacemaker and developed the 1911 to solve the problem. Incedentially, you can shoot .38 Colt through a .38 Special, but I don't think .38S&W would chamber.
Magtech makes the standard 145gr LRN .38 S&W for about what a box of medium quality .38 special would go for. I just bought a set of dies and some Starline brass. Lee carbide dies will run you less than $20, and come with the dipper and load data for 145gr HBWC bullets. it works very well, if you do decide to give it a try.
