Crimping Reloads

Reloading a bunch of 45 ACP this week.

For 9mm, I've generally done a very light roll-crimp. Same on 45 ACP or should I make it a heavier crimp?

Since both 9mm and 45 ACP headspace on the case mouth, they both should have a very slight taper crimp. It should be just enough of a crimp to remove the belling from case-mouth expansion.
