Don't know about everyone, but all my cast revolver bullets, 357 and 44 Magnums, get positive roll crimps into their crimp groove. I've been reloading .44 Magnum since '88 and all my reloads, with cast or jacketed bullets, get a good roll crimp and I discovered Redding's Profile crimp mebbe 10 years ago and use it for my many of my 44s too...

Not a big deal. I've been using the "rule of thumb for crimping" for over 30 years and 90% of the time it works for me; bullets with a crimp groove or cannalure get roll crimps. Bullets without a crimp groove or cannalure get a taper crimp. K.I.S.S....

Just wondering, you say your bullets are .433", have you measured your cylinder throats? If your throats measure .431" the .433" bullet will exit the cylinder at .431"...
