The part that will need the most attention, will be the sear spring, located inside the action, at the top. 

Those are, a lot of times, way to strong of a spring. I got my wife's plain trigger, HW, down to 2.5 lb, by reducing the thickness of that spring. I also polished the other engaging surfaces, too.

svartkruttgris#369 - You are spot on (but Frank suggested main spring is going to be required).  Embarrassing, but when I did the chamber casting...it was heck to "bang it out"!  I got that silver casting stuff all in the action by adding too much. Oh the fun of fixing that mess...and tore up my black powder bench loading rod beating that casting out.  Felt pretty low that day...Midway gunsmithing videos don't look like my work...

I had to take action apart (I had been dreading it) and I cleaned/oiled (not polished) the parts before reassembling (yeah, I found a U-Tube video on how to do re-assemble...). Trigger was a little better but still stiff.

Mr Frank, I remember there was a little spring that was at the  bottom of the action...above trigger floor plate...what in the world does that little puppy do? Not sure I  got that one installed correctly.

Frank, when next I take it apart, I'm going to message you and send pictures. I appreciate your knowledge and thank you for the guidance. 

Please don't send me an invoice!   

I'm not a total idiot, i like shooting more than gunsmiting and bullet making, but I'm getting more patient with age (I'm a young 52) and I'm getting more interested in this fine art of the shooting sports...but it ain't cheap. 

I love flintlocks for there simplicity and they are cheap to shoot (once you bought your $2k plus custom rifle).  I used to think the Flintlock was the "fly rod" of the rifle world.  But changing my mind on that...this ASSRA stuff is the fly rod and the bullet knowledge here are the "fly-making" stuff to catch the big fish (e.g. little groups at distance).

Thanks

I fill my extractor cuts with children’s clay.  It holds up well under the heat and is fairly easy to pick out. I am sure there are more elegant solutions y

Vall I just pack the area with cleaning patch material and when done just simply pull it back out.

Learning to pull the "guts" out of and back into a HW is just a matter of a little practice. The flat-spring action is a bit more of a hassle than a coil-spring, but still very easy once you get used to it. 5-minutes for the flat-spring & 3 for the coil. Quick & easy once you get the hang of it.

If you aren't a member at the River Bend GC am sure you are aware of it. They shoot BPCR & BPTR mid-range the 3rd or 4th weekend of the month (check their calendar). While your 32-40 is not appropriate for same, they will be a number of experienced High Wall shooters at the match who can help you with the heavy trigger and the bullet issue. If you are new to casting they will help you get started. That new RCBS pot with the PID controller would be a great place to start. Casting is faster & easier than it seems from the sidelines. If you have the mold someone will likely invite you over to show you how to use it and help you cast 50, or so, bullets to get you started. Single-shot rifle shooters are like that. If you get there, ask for Kidwell or CO and tell them SSShooter sent you.
