No, I believe that is correct other than I do not think rimmed cartridges "head space" on anything as they are not chambered in the barrel (except some odd ball 38 semi autos and Desert eagle type guns) So for revolvers, yes roll crimp if they have a cannelure. If they don't, I still run them through the LFD
But I am a Head Case so could be wrong
