If loading black, you may want a bullet that has fairly large grease grooves. and the "lube of your choice" may be good for smokeless, but not all lubes are created equal regarding use with black powder. The gun should shoot more than 12 rds before accuracy goes south or the gun gums up. There are good recipes for black powder lube, or several good commercial lubes intended for use with black, like SPG.
You may be able to us some of your ACP die set to load 45 Colt, but the shell holder wil be different, as will all the die settings other than sizing because of the length difference, and the crimp may not be good for the Colt round unless it's able to o a heavy roll crimp. Sizing and expanding dies would probably work OK.
Most guys that shoot black much seem to like abut 1/8" of compression of the powder. Many use a compression die (some use the expanding die for this) before seating the bullet so they arent mashing the bullet when seating. Using a drop tube helps get more powder in and settled well.
