I crimp as a seperate step using the seating die that came with the set.
I always measure and trim any brass that is on the long side.
What I did with my seating die was to set the die for the crimp I would like and lock it with a Hornady lock ring (these are LEE dies).
Now take a large washer (mine is about 1/8" thick) that will fit between the lock ring and the press and screw the die on top of that washer.
Seat bullets with the washer in place. After you finish up the batch of bullets take the die out, remove the washer, screw the die back in. Make sure to back the seater off a bunch of turns before using. The die is now in your crimping position. Crimp away!
cheap and lame I know, but it works!
