Not really your advice is to send more $1.50 a pop bullets down range with new cleaning methods that just dont hold water. Ive shot many 5 pound bottles of the stuff through at least 4 brands of rifles. Swabbing has never been an issue when using Blackhorn. Number 1 cause/s have always been poor sabot fit and not waiting long enough between shots.
Regular solvents/cleaners wont clean sabot residue?...Obviously you never tried really hot water and a bore brush. JBs or Montana Xtreme bore polish. Sabot residue to the point of causing accuracy issues is exceedingly rare with modern sabots. Typical cleaning each outing and a good scrubbing a few times a year with something like JBs is all most of us need unless you blow a sabot. You wont even be on paper at 100 yards if you blow a sabot.
BTW dont tell the majority of inline match winners at Friendship they must have some magical seating pressure and tight projectiles to shoot awesome groups. Most are using sabotless and conicals that are no where near as tight as most sabots. Firm, consistent and repeatable just like any other powder.
What I gave were techniques aimed to isolate common problems. Nothing was said about cleaning methods except to check both clean an dirty barrels.Plastic solvent is a quick check that includes that. If you have shot so much and don't know that different rifles will shoot different bullets better or worse you have not learned much You on the other hand have given nothing except how great your are.Typical of the new members plaguing this forum that can only brag and chest thump with out offering good advice . I'm not going to argue with you,let the OP decide what works for him or not. Go find someone else to chew on.
