Alan,
It's actually a taper/roll crimp hybrid. It is possible to get a slight galling condition with the brass and die if set too heavy. Check your cases as they come out of the die and adjust accordingly. Sometimes with cast bullets, the little bit of bullet lube near the case mouth from the previous seating operation, negates the problem.
Have fun!
