As far as crimping, I usually go .474-.476 depending on what I'm doing. Pretty sure Hoot experimented with taper crimping, and found you can go well past that (I want to say into the low .46's) and still headspace properly. Slowly take it down and thunk test each time.
Since they don't have a cannelure, don't go below .476 crimp. There will plenty of time to investigate outside the nine dots once you've got some time under your belt with this caliber.
