Hi Charlotte,
I am a bit of a late comer to this thread but I will toss in my two cents. Recalling other threads regarding your rifle I am sorry to see that you are having such problems. A rifle that shoots well is a joy to own and work with, one that does not will test every fiber in your soul. My suspicion is your soul fibers are feeling pretty tested.
Following the thread, you have looked at the usual suspects, bedding screws tight, trigger tight, sights tight and repeatable. While one person mentioned the possiblity of weak springs causing light or erratic hammer strikes that does not happen often on a Match 54 action. Every once in awhile you might hear of a Match 54 breaking a firing pin but only rarely. Swapping out firing pins should not have affected anything either. (Again, pretty simple system, very little to go wrong.)
While I have never seen a case this dramatic (tosses 7s) I have seen the occasional lead buildup in the barrel. It is smooth and shiny so does not really show up as fouling per se. With my own barrels I clean them routinely (every 100 to 150 rounds) with typical solvent (Hoppes, Match Winner etc.) then every 500 to 1000 rounds I will clean with a water based cleaner. Interestingly, I can have and apparently clean barrel with the oil based solvent then still get plenty more "dirt" with the water based stuff. (If you are intersted in giving it a try PM me for more details) I will say, from what you describe I am not optimistic that would solve the problem.
I am focusing on the part where you say you get soot streaks on the cases. For a single shot bolt action rifle this is very unusual. SK is a good quality ammunition so I would not expect significant case variability or small cases. I have seen different boxes from the same lot of ammo shoot differently but it sounds like you have shot this ammo throught several different rifles and the only place it does not shoot is in your 1907, so strike that possibility.
You mention taking the rifle to Chuck Gartland, which had I weighed in earlier would have been my recommendation about 10 posts back. Take a few of the soot streaked cases with you when you go. He might find them interesting. (You can look at the relation between the hammer strike and the soot streak to see where the chamber might not be right.) (Also, if the soot and hammer strike are always in the same location that does identify the chamber as the issue, if it moves around then it may be the chamber, or it may be something else.) Hopefully Chuck can find the gremlin(s) and exorcise them. From what you describe he might recommend the barrel be removed, the back 3/4" cut off rechambered and reset. (You used to be able to do this with Anschutz barrels I assume you still can.) This a also a great opportunity to get the head space tightened up to about the minimum possible clearance.
So I have ambled on here for a few paragraphs to finally say, good idea, take it to Chuck. Good luck with it, you seem to be trying very hard with it, you deserve a break in your favor.
Cheers,
