Started reloading for my 6.5 RPR and AR10. 140 grain Hornady SST has a cannelure, but when loading to COL spec’d in load data the cannelure is about .3” forward of case mouth. My understanding is that with Lee FCD I can crimp without the cannelure, but aside from looking a bit odd is there an issue with the cannelure not matching up with case mouth? Am I correct in thinking that COL is more important for pressure/safety considerations?
