Just found something that may be of interest...I like the idea of a crimp on the .400. My seating die won't roll crimp the short .35 Whelen brass and the Hawk bullets don't have a cannelure. I ordered a .405 Win Lee Factory Crimp die which did not work when putting the cartridge in the shellholder on the press. The shellholder contacts the press too soon and I would be crimping the bullet itself right in front of the case mouth (you can see in the pic below where I did just that with one of my dummy rounds).

Simple solution is to swap the shellholder for a quarter. Doing that I was just barely able to put a factory crimp on my short .35 Whelen Brass and the 350 Hawk. The QC brass is plenty long to crimp nicely with enough length to adjust the die for the desired level of crimp.
