Crimping 45 ACP?

Just seeing what’s out there. Reloading some 230gr fmj .45 ACP for the 1911 and was wondering if you taper, roll, or leave it be? Personally, I’ve always tapered just slightly to help feed.

It headspaces on the case mouth so I just straighten the case. More than that can lead to mega trouble. The expander ball needs to be slightly undersized to prevent the bullet from setting back into the case from recoil. You should see the bulge from the base of the bullet from outside the case.
