Just out of curiosity? How important is a cannelure for revolver cartridges? Especially with a Lee fcd? I think my only experience loading non cannelure bullets were 9mm HSTs which are a little undersized as is. For actual . 357 bullets the case tension would be better.
Specifically I'm looking at the rmr smiley face bullets. They're almost as cheap as the cast bullets I normally shoot
