I plan to use this set just for gunsmith only tools, cleaning supplies,
and parts.  It will clean out several drawers and a couple square feet
of surface on my front office work bench.  I may put some reloading
supplies and a couple presses in it as well if the bottom drawers are
deep enough.  Well, until I get the file cabinets out of the file room,
and get a proper work bench built in that room.

Do you know a good non-fouling target load for a "BP-only" 45-70 Sharps or original Trapdoor?

 I do have a BP loading manual somewhere that I can use to look up some loads if you like, but you may be more comfortable buying your own copy than taking the word of "some guy on the Internet."
 

On page 308 of the Lyman Black Powder Handbook & Reloading Manual, where the cartridge data begins it says, "All loads are measured by volume. All loads completely fill the case and are compressed by the bullet 1/16th inch.  If a wad is to be used beneath the bullet base, loads should be adjusted to give the same 1/16th inch compression."
This is what I thought.  You can get over pressure with black powder if it is loose in the cartridge / chamber.  That is why muzzle loaders try to always be careful to fully seat the bullet (and patch) against the charge.  Failing to do so can result in ruptures in old weak guns and bulges even in newer reproduction guns.  Yes, even with an otherwise correct charge.
I do not know if Triple 7 is subject to the same issues, but except for being slightly hotter its a direct replacement.  It should be used the same except for adjusting the volume down and adding a spacer or wad to get the muzzle velocity you normally would with a similar BP load.
I'd been looking into this for possible use in reloading 32SW.  32SW Long is still available and I may be able to order 32SW Long brass and cut it down for those old vest 32s.  There are also modern powder loads for 32SW and 32SW long, but I don't want to wind up with 50 different powders on the shelf.
I can look in my other manuals to see if there is a modern powder load for your cartridge, but you asked about BP sub.  Triple 7 would be my first choice.
