Any experiences with accuracy differences for reloads with a Cannelure case and the bullet finger seated to the Cannelure vs a case with no Cannelure with the bullet factory crimped?
Never shot any Cannelure fixed cartridge reloads in any caliber and all reloads have been factory crimped

John Boy, I'd like to help you out, but I've not done any of the things on the list for comparison with one another. Finger seating, crimp, or seat to the cannelure. Maybe that's why the lack of responses. 
For whatever it means, my cannelured cases don't seem any different than the rest without them in my fixed loads.

The cannelure typically blows / irons out after having fired the case so how is one going about putting it back per the original factory specs. Or I might ask how is everyone establishing a baseline to reference off of so all of the tests are relevant from one person's tests to the others for the sake of establishing some means of exacting compared results. What is it that I might be missing along the way and how is everyone putting that factory cannelure back per the original specs?
I understand the crimping process but again how does one assure that the crimp pressure is the same from one person's test results to the next?
