I'm hoping it'll work like Unique, but meter better and give more consistent velocities. The goal is to have "one powder to rule them all."
I had set the crimp die up when I was loading 158 Berry's RNs seated to where the ogive just begins to curve in. That's the bullet I used when I was shooting IDPA SSR and the goal was to have the case mouth follow the ogive so the round would smoothly slip into the chamber on reloads. I just loaded 100 rounds and adjusted the crimp so the case mouth is almost to the bottom of the crimp groove. It was a pretty big adjustment. The profile crimp might do better - I have one for my .41 Mag die set - but I think this should work fine.The Redding profile crimp die is the best thing since sliced bread as long as you have a groove to crimp into.
