Introduction
     The single most important factor in consistent accuracy is the management of black powder fouling.  Because of their chemical compositions, black powder and the black powder substitutes leave a hard residue (called fouling) in the bore after each shot and unless steps are taken, layers of this fouling build up with each shot until the stuff literally burys your pistol's rifling.  The traditional practice of plastering grease over the tops of loaded chambers is supposed to help slow this buildup, but every shooter knows that this practice actually has very little effect on fouling buildup. 

     Why is it important to be concerned about fouling burying your rifling?  Buried rifling can not spin your bullets as they travel down the barrel and without spin to stabilize their flight, your bullets will be all over the target or miss it altogether.  This is a very bad deal and takes all the fun out of shooting, so we need to either clean after each shot (who wants to do that?!?) or (better yet) find a way to manage fouling so it does not build up and affect our pistol's accuracy.

     The good news is that there is a simple way to transform hard fouling into a soft, greasy substance that does not build up in the bore and cover the rifling.  This method actually works and is much less messy than the traditional method of plastering grease on the outside of loaded chambers.  In this article I present three simple and convenient loading techniques and by using any one of them, you can easily achieve what I call "good fouling management."  If you practice good fouling management, you can make it so that your revolver’s accuracy is limited only by your ability to hold it on target, not by the fouling that builds up as you shoot.  You will also notice some other advantages besides improved accuracy if you use my loading suggestions, but I'll mention them later.

Fouling Management
     We can achieve good fouling management by the use of the right substances applied in the proper manner.  In the following paragraphs I will present three ways to load the B.P. revolver to minimize fouling and maximize accuracy.  All three methods reject the traditional practice of (what I call) ‘Glomming on Crisco’.  By this, I mean thickly coating the outside of the loaded cylinder with Crisco (or ‘Spit Ball’, Bore Butter, etc.) as is recommended by just too many black powder shooters and "how-to" books.

     What I am about to suggest is very controversial because every "expert" will tell you that you MUST coat the outside of the loaded chambers with grease to prevent chain firing and to "lube the bore".  Believe me, Glomming Crisco absolutely will NOT prevent chain firing (see first article on chain firing).  As for lubing the bore, after the first shot, all the grease is blown out of the remaining chambers and subsequent shots get little or no "lubrication."  Next time you load the conventional way, just look at your cylinder after your first shot --- is there any grease remaining?  No, it was all blown away and the subsequent shots will do nothing but build up hard fouling in the barrel.  Don't bother with greasing the outside of a loaded cylinder.

     To keep fouling soft, your revolver’s bore needs a residual of grease after the bullet passes. What the bore really needs is grease behind the bullet.  Grease on top or on the sides of the bullet is pushed out as the bullet leaves the muzzle, doesn't  mix with the fouling already in the barrel and does nothing to soften the fouling left behind as the bullet passes through the barrel.  I have experimented over and over with this and my results can not be argued with.

     Before I continue, let me submit a proposal for your consideration.  I think that we use the term "Bullet Lube" way too loosely.  Crisco, lard, Bore Butter, Spit Ball, Etc. should Not be thought of as "Lubricants", but rather as "Fouling Modifiers" or "Fouling Limiters".  They do what they do not by reducing friction, but by transforming hard fouling into soft grease.  How about calling them "Fouling Sanctifiers" for turning bad fouling into something good?  From now on, I'm going to try to avoid using the term "lube" altogether and call it what it is, grease.

So here are my three ways to "properly" load the revolver for
 maximum accuracy and minimum black powder fouling: 

     Regardless of which of the following methods you use, first wipe off the top of your chamferedcylinder with a cloth then carefully load each chamber with FFFG powder using the "clean powder management" suggestions I wrote about in chapter 2.  Begin by filling each and every chamber with the proper volume of powder.  Brush away any grains of powder that might be loose on the top of the cylinder or on the sides of the chambers after all chambers are CLEANLY loaded with powder.   

Before I go on, let me say something about the volume of powder you should use when loading.
     You must never load the chambers with too much powder or use too much filler or the tops of your bullets won't be flush with the cylinder.  If a bullet is sticking up, the cylinder won't rotate and your pistol will seriously jam.  I don't know how much powder to suggest for the .36 caliber "Navy" pistols, but the .44 caliber "Army" pistols must not be loaded with more than 30 grains (by volume) of real or substitute powder when using round balls and no more than 25 grains when using conical bullets or if your pistol has a brass frame.  When using thick wads, use even less.  For the "Navy" caliber, you will use much less powder (20 grains maximum I think).  You may want to work up from smaller charges (around 20 grains for the Army caliber and 15 for the Navy caliber) to see how deeply the bullets seat and to see if maybe you like the reduced blast and recoil better.  Believe me, you do not want to use so much powder that the bullets are too close to the top of the cylinder or you may be in the embarrassing position of having to use a sharp knife to peel away at the tops of your bullets until your cylinder fits.  Not a good thing to be doing at the range with everybody watching.

     By the way, everybody should know that it is impossible to load a chamber with so much powder that the pistol is in any danger of "exploding" or harming you in any way.  This can't happen when you use black powder or substitutes because small volumes of black powder just can't create dangerous pressures and even Walker Colt chambers don't hold that much powder.  It can sure happen with fast burning smokeless powders, but not with black powder.  As mentioned above, the only problem with putting in too much black powder is that you won't have room for the slug and it will stick out and jam the pistol.  Yes, you can overload a brass framed revolver and eventually cause it to loosen up, but the pistol will never explode nor will you ever be exposed to any danger no matter how much powder you stuff in there.  

     So, what about underloading a chamber, is that possible?  Under certain conditions, YES, underloading can be a problem because a misfire or a very weak shot can happen with small charges. When a misfire or a very weak shot occurs, many times the slug is propelled into the barrel, but does not exit out the muzzle.  This is a very bad deal.  The next shot taken with an obstructed barrel will cause the trapped air between the two slugs to rise to an extremely high pressure and can cause the steel of the barrel to bulge and many times, to actually split.  Even a badly split barrel is unlikely to hurt the shooter, but it will destroy the revolver and certainly make you feel real dumb.  It is my sincere opinion that if you like shooting "squib" (low power) shots, you should load with real black powder only.

      The reason I say that small charges should only be done with real black powder, is because black powder ignites so easily so that even as little as 15 grains will fire and propel a .44 slug out the barrel.  On the other hand, substitutes, especially Triple Seven, are much harder to ignite and the hot gasses from the cap have a really hard time igniting just a short length of it.  Again, it is my advice to use full or nearly full charges when using black powder substitutes and always, regardless of the powder you are using, don't shoot the next round, but check your barrel for obstructions if one of your shots feels weak or a chamber fails to discharge fully.

This just added to my article:  
There is a product I have just learned about and I think it is worth trying.  I just found out that Pyrodex comes in  pellets  that have the same volume as 30 grains of black powder and are made especially for .44 caliber revolvers.  These pellets would make loading very fast, but more importantly, your pistol would load very cleanly with no possibility of spilling powder on the top of the cylinder.  Because these pellets come pre-measured, you can't overload a chamber so the bullet sticks out.  These pellets are kind of expensive, but you might want to give them a try anyway.  Be sure to load the dark, black powder side toward the nipples otherwise you might get a misfire.  If you do decide to try these out, you will still need to follow the instructions below with some kind of wad or spacer and grease behind the slug.  The only thing the pellets do for you is make loading powder cleaner and faster.

Should you use these pellets in a brass framed .44 revolver?  They would be equivalent to a full charge of black powder and would likely over-stress the brass frame.  Use of them in brass framed revolvers may not be a good idea, in my opinion.  


Here are the loading techniques I'd like to suggest:

Grease Behind the Slug Method No. 1
     After putting in the right amount of powder in each of the chambers, take commercially manufactured felt revolver wads and insert one in each chamber.  Seat the wads on the powder with the rammer (see the note below).  The manufacturer impregnates these wads with a "lubricant", but in my opinion, they do not contain nearly enough or the right kind of fouling modifier.  Using wads is great for two reasons.  First, it sweeps the chamber walls of any powder grains that might be there (helping to prevent chain firing) and it provides a moderate amount of space for excess 'behind the bullet' grease that might otherwise contaminate the powder.   If you are shooting very light loads, you may want to add some corn meal or Cream of Wheat filler to each chamber before seating the wad.

Just lately it has come to my attention that the inexpensive brass framed .44 Pietta revolvers have undersized rammers that don't fit the chamber diameter and so they can not seat the wad squarely on top of the powder.  If you have one of these pistols, I suggest you make yourself a wooden dowel of the right diameter so that you can use it to seat the wads properly.

Grease Behind the Slug Method No. 2
     At a hobby store, buy a 15/32 inside diameter brass tube and a roll of sheet cork.  Sharpen the end of the brass tube and punch out some cork disks.  Load the revolver as described in Method 1 above only using cork disks instead of felt pads.  This method also sweeps the chamber wall free of any grains of powder and it gives room for excess grease that might otherwise contaminating the powder.  This method will not be so forgiving if you use too much grease.  Again, if you are shooting very light loads, you may want to add some corn meal or Cream of Wheat filler to each chamber before seating the wad.

Grease Behind the Slug Method No. 3
     The cheapest method I have found to reduce the bad effects of fouling is to pour about 10 grains (by volume) of "Cream of Wheat" or dry corn meal into each chamber on top of the powder.  Use more if you are shooting light loads.  In fact, this is an excellent technique if you are shooting light loads with or without a wad.  This method is only to provide a space for excess grease so it doesn't contaminate the powder, but it does not "sweep" the chamber walls for loose powder grains that might be there like the wads do.   However, if you were careful, there shouldn't be any powder grains sticking to the sides of the chamber anyway.  This is a good method because it gives you just that much more space between the bullet and the powder so that if you use too much grease it has a place to go.

When you have all the chambers loaded, regardless of what method you used, here's what you do next:
     Smear a small amount  of Crisco, Bore Butter, Spit Ball, lard, tallow or a similar kind of grease on the tip your index finger and then wipe it across the top of a chamber so as to leave a small (and I mean SMALL) amount of grease clinging to the sides of the chamber.  Do this until all six chambers are "lubed" in this manner.  Note:  If you use too much grease, it will get past the spacer and contaminate the powder when the ball is rammed down and the resulting shot might be weak. If you notice that your last shot was very weak (a quiet 'pop'), stop shooting and check the barrel to insure that a bullet isn't stuck in there.  Next time you load, use quite a bit less grease.  If you don't use quite enough grease, fouling will slowly build up, but you can experiment with that.  You will have to experiment a bit to find just the right amount of grease to use.  By no means use the same amount of grease between the wad and the bullet as people use when they plaster grease over a loaded cylinder.  It is probably best to start out with too little grease than with too much.

     The next step is to place a ball (or slug) over a chamfered chamber, ram it home and repeat until all chambers are loaded.  Use only enough rammer force to gently seat the bullet and try to avoid jamming it down hard.  It is important to seat the bullets, but excess force does no good at all.  

     Speaking of rammer force, it has come to my attention that one of the factors (besides overloading) that causes brass framed revolvers to become loose over time is stress from excessive rammer force due to using oversized slugs, unchamfered chamber mouths and squeezing too hard on a loaded slug.  If you have a brass framed revolver, I suggest you be mindful of the rammer force you are applying and do whatever you can to minimize it.

Grease may be forced into the top portion of the filler material, but there it can not affect the powder below it.
Because of ignition failures, I strongly recommend using only real black powder in these kinds of loads.


If you have put in too much powder
     Be absolutely sure the bullets are at least flush or below the level of the cylinder or your pistol will jam and it may be very difficult to remove the cylinder.  I can't stress enough how important it is to not overload your chambers or the bullets will fail to clear the top of the cylinder and stick out.  If you can't get a bullet down all the way flush, don't try to rotate the cylinder, but immediately remove the cylinder from the pistol.  If you try to rotate the cylinder with a slug sticking out, it will jam up and if it is a Remington type, it will be nearly impossible to get the cylinder out (just knock out the barrel wedge if your Colt is jammed).   Once out of the pistol's frame, the slug may be carved down with a sharp knife or (better yet), remove the nipple (if you brought your wrench) and remove 10 grains or so out the rear, put the nipple back in and then try to reseat the slug deeper.  Be sure to kick yourself as hard as you can so you won't make this stupid and embarrassing mistake ever again.  Sure, we all want a big jolly blast, but overloading is just stupid -- I know, I've been there and done that.
 
Now that we have that out of the way, let's assume that all the bullets are seated properly and let's continue.

A final and important step before capping your revolver
     OK, here's where it gets controversial again.  DO NOT, repeat, DO NOT put any "lube" (grease) on top of the loaded chambers after the ball has been seated.  I know that everybody tells you to do this, but just don't.  Any "lube" you put up there will just make the top of your cylinder sticky thus attracting grains of powder when you reload and it is loose powder grains that are responsible for the vast majority of  chain fires.  Please believe me, putting "lube" (grease) on top of chambers does not prevent or even lessen the chances of having a chain fire, it just enhances their probability.  I invite you to experiment for yourselfand see if this is not true.   Now, having said that, if you range is run by some kind of a dictator who absolutely insists that you put grease over your loaded cylinder, go ahead and do it, just to keep peace.  It won't help anything, but it doesn't hurt much either and it just isn't worth making a fuss over.  Speaking of capping, I feel this is such an important and potentially hazardous operation, I want to say a special word about it even if it is off the subject of grease and fouling.

A special word on capping
     It has been my experience that capping is the most dangerous time in the whole reloading sequence.  My best friend severely injured his hand and people standing nearby could have been hit when he used a wooden stick to jam on undersized caps and one of the chambers went off.  Under no circumstance use undersized caps and under no circumstance hold the pistol by its front end while capping.  Pietta suggests you use No. 10 caps, but my experience is that they are too tight and that even experienced people (people who should know better) will get frustrated and use extraordinary means to force them on.  One of the absolutely worst things you can do is to use a stick or (may the gods forbid!!) a metal rod to jam on an undersized cap.  That is a disaster waiting to happen and sooner or later a chamber will go off, so please, don't use extraordinary force to get caps on your revolver's nipples and, for the love of Pete, don't use any sticks or rods either - fingers and thumbs only.  Use No. 10 caps only after you are absolutely sure your revolver's nipples are the right size to accept them.  In my opinion, it is best to use No. 11 caps and squeeze the skirt a little if they are a bit oversized.  Don't worry about a lost or loose fitting cap causing a chain fire because experiment after experiment after experiment has convinced me that this is just another myth and old wives tale.  Lost or loose fitting caps DO NOT cause chain fires and this is something you can experiment for yourself if you doubt it.

Finding the optimum amount of grease to use behind the bullets
     One of the best ways to find out how much grease to use is to take your cleaning rod with you to the range.  After loading with just a small amount of grease behind the slugs, take your first six shots, then put a dry patch on your jag and run it down the bore.  If it glides smoothly down, you are probably using the proper amount of grease behind the slug.  If it feels dry and rough, put some grease or jojoba oil on a patch and let it dissolve the hard fouling.  When the barrel is clear of fouling, reload but this time use slightly more grease.  Shoot another six or more shots and then put a dry patch down the barrel again.  Keep doing this until you determine how much grease to use.  By the way, you can use a lot more grease when shooting round balls than with flat based conical bullets for the same volume of powder.  If you are shooting conical bullets, you may have to reduce the powder volume to give room for the grease.  When you ram in the slugs, try not to use so much  force that the grease is squeezed past the wad and into the powder. 

The improvements you will notice shooting with grease behind the bullets
     When you load by means of one of the methods described above, you will notice three important things.  First, you will be pleased at how much more accurately your pistol is shooting especially toward the end of your shooting session.  Second, it will take much longer for your cylinder to start feeling sluggish and you will be able to fire more shots before it binds up altogether.  Finally, cleaning your revolver’s barrel will take much less time and will require little or no solvents and NO soap and water.

A test to see if you used enough grease
(if you didn't take your cleaning rod with you to the range)
    When you get home and you go to clean the barrel of your revolver, start by using a dry patch.  Simply put a dry patch on your jag and run it down the bore.  If it slides down easily and comes out covered with a coating of black, greasy, soft goo, Congratulations: you are using the proper amount of "fouling modifier" (grease).  If the patch will not easily go down the bore and/or the bore feels rough as you ram the patch down, you probably have already noticed that your shooting wasn't’t very good and you need to use more "fouling modifier" (grease)  next time.

Substances you should and should not use when loading your revolver
     As a final note, all experts agree that you shouldn't coat your bullets, your revolver’s bore or the cylinder chambers with petroleum based oil or grease or alox.  Everybody recommends using eatable fats that contains "natural" substances.  Products that are proved to work include tallow, Bore Butter, Crisco, Spit Ball and if it is cold out, lard works well and smells great.  Evidently, eatable fats dissolve and soften fouling whereas petroleum derived oils are reported to thicken into a kind of tar.   Lately I've read where it's OK to use water pump grease, but water pump grease contains lithium and lithium is toxic.  Thanks, but I'll leave water pump grease to others to try as I'm sticking to the traditional non toxic stuff.

     Since writing the above I have made up a custom blend of about 85% Crisco and 15% beeswax and the stuff works way better than anything I've ever used.   Because it has a high melting point, I can use it on warm days and it doesn't run.  It also resists blending into the powder and so I can use a lot more of it under the slug. 

     To make up a batch, just melt the grease using low heat and add the beeswax - the substances blend instantly as soon as everything is melted - pour the liquid mixture in a metal or heat resistant glass shallow jar and let it cool.  Depending your local climate, you may want to use even more beeswax to increase the melting point.  You can easily remelt and re-blend the mixture until you get it just right, but be careful and use just enough heat to barely melt the beeswax -- a grease fire on top of a stove is not a good thing.

     How well does this mixture work?  During my last shooting session, I was just amazed at how clean my bore stayed and I was even more amazed that the grease got into the bottom of the chambers so that there was no hard fouling build up down there either.  When the charges go off, the stuff must atomize and get everywhere.  My already easy cleanup was even easier and took fewer dry patches as there was hardly any residue in either the barrel or in any of the chambers.  I highly recommend experimenting with a mixture like this.  It's cheap, easy to make up and it works fantastic in revolvers.
