Hello, Here is a question for the black powder experts:  I stopped shooting black around 1990.  I was shooting an original Win. High-Wall .38-55.  After reading of how good the various black powders were in the late 19th century..less fouling, cleaner burning..I became dissalusioned with the then available Goex, and started loading smokeless.  Now fast forward 20 years..I have heard about the clean burning Swiss powders and the new types of Goex.  I might be buying an original Rem. Mid-Range..Has new 34" 1/2 Oct. custom brl. in .40- 70 Str.fitted...Original .44-90 has mint bore & numbered to gun, goes with deal.  I have made up my mind to use only genuine black in this rifle for safety & traditional reasons.  When shooting black  in a roller...do you need to disassemble action for cleaning?  Are ther commercial cleaning solutions that are safe & effective?  I used to use the concentrate Black Solve..mixed with water.  Are there better ones?
How about leading..after cleaning out B.P. fouling..do you go in there to make sure no leading  that might trap fouling underneath?  What do you use for this?  Would Ed's Red work?   
   What grain size would you recommend for .40-50 B.N. & .40-70 Str?
Are grease cookies still being used? (when I was shooting black..blow tubes weren't even out yet).  I appoligize for the lengthy questions..it's just that I have been out of circulation in this field.  Thank you so much!

Good advice all will add a few things.  I wax my rifles used with Black powder, plain old floor wax. Keeps cleaning fluids out of the cracks and crannies.

Blow tubes came into use when BPCS matches started. Relays are short and it's a good way to shoot a string without coming out of position.

Having shot the same rifle BPCS then converting it to a Schuetzen using black my opinion is blow tubes are not as effective as a wiping rod between shots, if the course of fire allows time to wipe. With a wet patch dry patch routine between shots there is hardly any clean up required at all after a session. I do go back to the rifle day after and wipe it again just to be sure.

Cases are another mater and to me a real pain to clean but it needs to be done. When shooting fixed and using a lot of cases I decap at the range dump them in a plastic bottle with water and some soap. At home fowling is soft and brushed out one at a time in the kitchen sink, then dried in the sun or warm oven.  last step I tumble, best if the are clean before they go into the tumbler. It's just to polish.

I use a blow tube for strings up to 10-12 shots if I have a time limit. If not I run a patch down from the breech end. use whatever solvent  works best for you. I like "Simple Green" and water (it is a household cleaner.) I've used the mixture of 1/3 Murphys oil soap, 1/3 alcohol, 1/3 Hydrogen peroxide and it works better than any other. I'm just a little leery about adding oxygen to Black Powder residue. It does work fantastic for cleaning your hands after getting Black on them. 
Whatever you use, the most important thing is that the bore is in the same condition between each shot. I don't run a dry patch down the bore like others do. instead I dampen my wipe patches the very same every time by using a spray bottle and spraying same amount on patch every time. 
For final cleaning I use same idea but continue to run patches untill they come out clean(usually two or three). Then I use a patch of "Shooter's Choice" down the bore. If there is any leading it will come out then. Next day or two  I run another patch of Shooter's down the bore again. If every thing is fine WD it and call it a day. I live in a high humidity area in SE N. Carolina. If and when I see that all the above isn't nessessary then I cut down on the stages.

Hello, and a BIG thanks for everyone who posted replys!  This forum is the greatest!  And a special thanks to ssdave about the use of Turp. never heard that one before...I really will try that a Big plus to it's use is the fact if some gets on stock, you won't have to worry about damage like some others on market.  Thanks boats about wax tip..I thought I was only one doing this!  Thanks again!

You can buy those off Buffalo arms I think.

Everybody has there preference mine is one wet one dry, all are good as long as it's the same every time

Because I'm a machinist what I use is water soluble cutting fluids for both between shots (1 wet 1 dry) and cleaning after. They are made to both lubricate and wet the surface as well as kill corrosion. I've use a few different brands and all do the job.

Talking about cleaning the brass after using B/P. I have started using a different way to clean the brass then I have ever used before. I have a drum tumbler (without media) that I put the brass into and add some water and dish soap. (Mixture of Murphy's soap/Hydrogen peroxide/ and alcohol would work better)I also throw in a scotch brite dish scrubber, seal it all up and let-er-rip come back in an hour and 
SHA-ZAM they are all clean.
