Ok, the Dardas bullet site which says only to use a Lyman M die for expanding cases on lead bullets, has a two step process that not only expands the case mouth but the entire case. The Lyman set comes with a "taper" crimp die not a "roll" crimp and I was wondering about the difference.
this is the reply I received from Dardas BC:
"Bullets need crimping only when they need to be crimped – not just because there is a crimp groove or ‘Simon Says’ to crimp. Crimping is only required if it is deemed necessary. A slight taper crimp to hold the bullet in position is ok as long as there is a crimp groove to accomplish this. Of course this only holds true for rimmed cases."
What are your takes on this? I'm getting more confused by the minute on the lead bullet loading procedure and what dies to use.
