	Apparently gunsmiths in the days of rifled jäger muskets, on up to the present made tools to scrape clean, the groove areas of black powder barrels. HAS any one had experience with this lost art ?

	Can be done on a muzzle loader using a cast lead slug in the existing rifling to guide a shimmed cutter. Usually deepen the grooves to clean up and float the lands. Strictly a hand process and more expensive than a re-bore and re-rifle. Many problems such as grooves not perfectly spaced, so new slug for each groove or choked or funneled bore. Would not do it again. Chuck

	Agree with CHUCK, I have done it, but would likely not try it again. CHRIS RGChristensen

	My 2 cents,linear drive to pull and push (reamer/scraper) to clean up barrel. Alinement might be a problem, nylon slugs instead of lead.New Hi-tech I know but so is fire!! 57thahc

	I believe Bobby Hoyt does this and other work on muzzleloader barrels. He works out of PA.

	I just want to save some original barrels with good clear rifling, the grooves are filled up. I tried chemicals and wire brushes. Thought maybe a scraper would work.

	It might work, but understand it is a rather painful chore, at least for me . Some of the muzzle loading forums might be more helpful. Chuck

Thought maybe a scraper would work. You might try Kleen Bore's Lead Away cloths. I've had very good experience with them. It takes a jag that's sized to the bore and gives a very tight patch to remove the lead. But it will come out in shards that amazed me! I use a regular patch under the Lead Away to get the jag fitting tight enough that I have to tap the cleaning rod with a rubber mallet to get started. I run them in from the muzzle, as the lead seems to build up more towards the chamber end. I always clean from the chamber, but this is the exception. It takes 3-4 runs through with a clean patch each time to get all the crud out, but I was amazed the first time my friend showed me how it worked.

	Particularly IF you are dealing with Leading, Turpentine works well on a TIGHT patch on a brass jag/quality rod driven thru the bore with a mallet. I use Tipton graphite composite rod/Jag that holds up very well to this deleading process. beltfed/arnie

	If it is leading, don't use the cast in place lead slug, else you will have a wonderful solder job of the slug to the smeared lead in the bore. Chuck

	I have tried jags of all types, turned to fit. The fouling buildup in these original BPCR barrels seems to be hardened powder and rust. I searched and found this : "Several years back there was an article in Gun Digest about restoring a muzzle loader by(I think) Hal Hartley. He cast a lead "lap" over a cleaning rod and then pushed it part way out of the barrel and inlet a hardened steel cutter to clean up the grooves. The first several passes just barely scraped out the rust. He kept adding paper shims to increase the cut diameter. I think after each pass he indexed to the next groove and added a shim after all grooves had been cut at the same depth. " Since there's already rifling to guide the cutter, this sounds good. Why would this scraper not work on a stubborn Sharps barrel ?
