After reading the ABC's of Reloading and the Speer & Hornady reloading manuals for a few months I finally bit the bullet and picked up a Dillon 550 from Brian Enos. Got it in 9mm with a 10mm full conversion kit and planning to add 45ACP in there later. Can't wait to get it and quit spending my afternoons hunting for ammo and paying out the ass for it. My question for the reloading crew, what is your powder of choice for those calibers? I'm shooting 147gr 9mm, 180gr 10mm, and 230gr 45ACP rounds.
