I have a small amount of 38 S&W brass that I would like to reload for my Webley & Scott War Finish revolver. RCBS offers 38 S&W dies for special order at a tune of over $100.00 a set. I have talked with several people and it has been suggested that 9MM Luger dies will work fine in reloading my 38 S&W brass. There is 5/1000th of an inch difference in the case dimensions. Can I do this????
