If the case mouth is within SAAMI spec, no setback problems, and reliability is good, then I usually won't bother crimping. (Revolver rounds, of course, get a roll crimp.)

I just make a dummy round, cycle it through the weapon, and then measure before and after with calibers. Sometimes, I'll see a 0.001 setback with plated bullets and pistols, which is no big deal. You could also push the nose of the bullet on a workbench to test for tension.
