Everybody offers dies for doing a taper crimp in a separate station.....which is where it should be done.    Some makers offer seating dies with taper crimps, some with roll crimps.  Older Hornady seating dies for autoloading cartridges used to incorporated a roll crimp, newer Hornady seating dies incorporate a taper crimp.  Lee offers seating dies with what they call a modified roll crimp which they say you can adjust to just do a taper crimp.

My opinion, (and most reloading manuals would agree) is that a taper crimp should always be done separately from bullet seating.   Roll crimping can be done in the seating step, but only if the bullet has a crimp groove, or you are crimping over the shoulder such as with a 38 wadcutter.

Thought you might like to know this if you don't already know :D ;D

NOTE: All Dillon Pistol Die sets include our sizer / decapping die, seat die and a separate crimp die. (Taper crimp for autos; accu-crimp for revolvers.)
