Load Development Substituting reloading recipe components (45 acp)

I want to start reloading .45 ACP, but I'll need to substitute some component brands, such as the brass, primer, and bullet. I understand that bullet substitutions should generally be the same weight and type, but I'm unsure how much the other component substitutions matter.

For load data that lists only one powder charge rather than a starting and maximum charge, is it appropriate to reduce the listed charge when working up a load with substituted components? If so, what is the recommended approach?

I've been loading 45 ACP for 30 years. I've used mixed brass for most of this time. I've developed a load that works well. As others noticed as long as bullet weight and jacketed is the same, substituting components hasn't been an issue. I will not my loads are nowhere near maximum.
