Ok I found a local source with a reasonable price on Berry's HBFP 124gr 9mm's for my 357 sig loading. Now I am reading that the RCBS dies I bought wont work for 357 sig? Some say they work some say they dont, I see why they say they wont. But being new back to reloading and new to this caliber I need to know if I have to put out another $50 for dies or if these will get me by? Thanks.
