How much do you crimp your handgun loads?

Loaders:

My lee handgun caliber dies include a crimp die, and I usually do a "light" crimp. That means I screw the crimp die adjusting knob in one half turn after it has contacted the case mouth. A full turn of the knob makes a "heavy" crimp. I'm sure ballistically it makes a difference in terms of pressure, but what kind of difference and how much? I'm thinking I need to try some heavy crimping to see if it makes much difference in accuracy? (Yeah, I know there are many factors to accuracy.)

Talk to me.

Life is good.
