Thanks for the info Wes. I would have liked to get a Lone Wolf barrel, but it seems they don't make XDm barrels. It will be mid December before I'll be able to grab everything up (barrel, conversion kit for Dillion 550, dies, supplies, etc.) I'll be coming to you for the brass and projectiles, hopefully you will have them in stock at that time. How fast are you able to push the Xtreme in the .357 Sig?
