One last update to this.
One piece of info that I didn't add was that for the most part, all I'll be loading in 45 Colt are Berry's 250g projectiles, which don't have a crimp groove. Anything FMJ or something I want some "umph" to, I'll just load 460.
With that said, and following the (always welcome) advice of you fellas here, I opted against the Lee FCD and just went with a Lee taper crimp instead. It was cheap, got it off of Amazon.
Persaonlly, I do not like the seat+crimp action on any of my loads so regardless of crimp the Hornady die can do, I'd rather have it in a separate step.
