Here's another vote for WW 231/HP38. I went thru many pounds of 231 loading .38's for PPC and it's a great powder for .45acp as well. Classic loader looks interesting but I started with a single stage and I suspect you'll be able to produce better ammo with a single stage or turret press. I'm not saying you can't get top quality ammo from your current setup, never used it. Just seems to me that unless you're working under severe budgetary or space restrictions you'll be better served in your quest for accuracy with a single stage.
