If you're loading volume, like I normally do, stick to the fold crimp. With a roll crimp on plastic shells, after it's shot you'll have to straighten out the end and that takes time. Also, in my experience, it's quicker to start and final crimp than it is to insert and set a OSC, pull it out of the press and then put it in a roll crimper and crimp. JMHO - Paul
