If you don't like the crimp from the Lee FCD, it is likely because you aren't testing your crimp's pull strength, and relying instead on "looks". The only crimp stronger than the FCD is the Lee Collet. Neither is sensitive to case length, but the Lee Collet is strong enough to deform bullets if adjusted too tight.

Joe @realguns did an extensive test of crimp solutions many years ago - even made a bullet pull force measurement device. The end result was that the FCD and Collet dies produced the strongest crimps.

I crimp for heavy 45-70 in a hard-kicking levergun and 44mag in a SW329pd.

Imho of course.
