Hodgden tells me not to use plated (Berry) bullets for reloading revolvers as they do not accept a crimp and revolvers must be crimped or the bullets will creep when firing rounds. But... I have been firing Geco .38 Specials thru my 686 without problems. They are fmj flat point with no crimp, 750 rounds of 158 gr and meeting IPSC Minor. Is this true? I would really like to use Berry's plated flat points.
