Ok, after talking to The Gunny A.K.A. GunNut, he describes a condition of shoveling the crud with the case mouth, during chambering.
The LeGendre Side Crimp does "NOT", take the flaring out of the case. You're going to need to do a separate operation and do a Taper Crimp as well, which will further hold the bullet up (bullet pull) and clean all the processes up and make the cartridge look good and function flawlessly.
