If youve ever had much time spent shooting black powder rifles you know about fouling issues and accuracy issues that result from the burnt powder residue / crud that builds up in the bore as fouling builds up can ruin consistent repeatable accuracy.
I've had excellent accuracy and no hint of patch burn or bore fouling in my 54 cal, 58 cal, and 62cal caliber hawken, rifles, but I load 90-110 grains of 2f down the bore, in my 62 caliber hawken, followed by a cotton ball, then a bore size dab,of a soap like lube, in my 54 cal, 58 cal, and 62 cal, rifles and 80 grains of 3f in my 54 and 90 grains of 2f in my 58 cal,
the cotton ball seats firmly over the powder charge, followed by use of a bore size glob of murphys flax soap then a patched ball with the patch having been soaked in flax oil paste
the result is the expanding powder gases compress the column and squeeze out the soap into the rifling and the cotton ball wipes the bore on each shot, the cotton ball keeps the powder dry but the soap paste gets hammered into the cotton ball so it seldom even smokes
use this process and you can shoot dozens of shots between minor bore cleaning, I get 2"-to-2.5" 3 shot groups with iron sites off the bench at 100 yards almost every time at the range, with many good muzzle loaded rifles.
you can use the same process with mini or maxi balls without the greased patch over the dab of grease, thats placed over the cotton ball and get good accuracy, if you prefer those projectiles, and still find the bore remains clean, obviously your rifles twist rate might require a bit of experimentation with loads. (lee makes a nice 500 grain mini for 58 caliber rifles)

many guys don,t realize that the original mini ball partly stabilizes by being distinctly nose
heavy / weight forward , just like a styro-foam coffee cup with a couple table spoons of sand in the bottom, if you throw it will always travel bottom forward, and wide open mouth to the rear in the arc it travels, the rifling imparts some spin increasing accuracy, but unlike the newer bullet designs the original mini does not totally depend on that spin to remain point forward, many newer designs are longer and not as nose heavy so they require spin to maintain gyroscopic stability, but if the skirt is deformed as it exits the muzzle, or the mini is not spun by the rifling, any chance of a consistent shot to shot impact point is destroyed

http://www.midwayusa.com/product/460281 ... uctFinding
if you have the correct style rifling and twist rate a mini or maxi ball is an option you might want, to consider, as they pack a good deal more down range energy than a round ball projectile and penetration,
but your rifles rifling twist rate must allow their use to stabilize them or accuracy sucks, do your research homework here.

first find your rifles twist rate,
simply mark a line on the cleaning rod,
with it fully down the bore,on the type of cleaning rod,
that allows the rod to spin as its inserted and with drawn,
with a tight fitting patched bore diam brush installed ,
and pull it out watching the mark rotate until exactly one revolution has been made then measure the difference in the length the rod extends from the bore.
if it was 14" out at the start and 40" out at one full revolution, then the twist rates 1 turn in 26"

example,
if the maxi ball pictured below is .588 caliber and 1.2" long it would take about a 42" or tighter twist rate to stabilize and 1 turn in 32 would be close to ideal

this is the same soap base grease in a larger container and cheaper per pound and easier to locate than the smaller container below

the soap paste is similar to peanut butter or axle grease as it comes out of the can, wet a patch with water and rub a bit into both surfaces to get a well greased patch that makes loading a patched ball fairly easy

just a bit of info, on hunting loads for larger bore hawkens
when I started out with a muzzle loading rifle I
was assured repeatedly by most of the older and supposedly more experienced guys that pure lead balls patched with a properly lubed linen patch were the preferred projectile in my 58 caliber hawken rifle.

but as is my nature I experimented with about every component available, and I tried a dozen different type patches , several dozen lubes and dozens of conical and mini and maxi ball designs in both my 58 and 62 caliber hawken replicas.
what I eventually found is that a bore diam ball cast from wheel weight alloy loaded in a well greased patch of about 1.25" diam, cut from used denim clothe and greased with flax soap paste was the most accurate out to easily 150 yards BUT only if loaded consistently, the same way.
both rifles prefer similar loads of about 90 grains of 2f powder , followed down the bore with a cosmetic cotton ball and a dab of flax soap , then the patched ball seated firmly over the powder charge , the cosmetic cotton ball acts like a seal gasket to prevent the flax soap paste from getting to the powder charge. loaded like that the bore stays fairly clean and powder fouling is minimized.
off a bench rest 2"-2.5" 3 SHOT GROUPS ARE COMMON
SOFTER LEAD BALLS OPEN UP THE GROUP SIZE SLIGHTLY i THINK SOME GET SLIGHTLY DEFORMED DURING THE LOAD PROCESS WHILE THE HARDER WHEEL WEIGHT ALLOY REMAINS FAR MORE RESISTANT TO DEFORMATION.
now Im sure the guys that hunt will point out the round balls from pure lead expand far easier and kill quicker, but in my experience the difference if any is marginal.

having a slight but concentric and consistent bevel on the rifle bore entrance greatly eases loading and reduces torn patches

THE PATCHED BALL MUST BE CENTERED IN THE LUBED PATCH AND RIFLES BORE WHEN LOADING FOR CONSISTENT ACCURACY!

while some people will think your old fashion or just not putting much thought into it,
a properly patched & lubed round ball has and will continue to be an accurate and useful projectile.
and Id suggest you try it just to check the rifles accuracy and consistency, with that option.
on my 62 cal hawken its shoots about a 2" hundred yard group off a bench rest,
all the other options , I've tried,are closer to 4"-5" groups , probably due to the less popular bore diam.
and slower 1/42 twist rate.
and yes its devastating on the deer Ive shot, so its not likely to be an issue with elk.
as always shot placement and a knowledge of the games anatomy and your judgement is critical.

If your concerned about burning patches and a fire hazard, as a smoldering patch might light the grass it falls into, first Id point out that the thumb tip full or dab of lube paste I mentioned that goes in between the cotton ball and lubed patch , tends to pretty much act as a fire retardant and soaks thru about 1/2 way, and unlike the patch directly sitting on the powder the cotton ball basically self destructs in a puff of fuzz as it leaves the muzzle and the patches them selves rarely look even singed because they are soaked in flax soap paste.
yes Ive occasionally seen a tiny bit of smoking debris but its not common, usually its just a patch with dirty grease on it and a bunch of floating fiber exiting the bore, after the ball exits
obviously the amount of soap grease used and the size of the cotton ball might effect your results
Take_a_knee said:
I always wondered about this. Glad someone tried it out. Thanks for posting this. Are these WW round balls any harder to seat?

the ball diam I use will not drop down the bore but requires very little resistance to almost no resistance to get the ball down the bore without a patch, once you get a thin patch of well soaked denim on the ball a short starter is required to start the ball, but once in the bore its not difficult to seal, as that dab of flax soap under the patch helps lube the rifling as its seated.

GOT A 50 CALIBER?
http://www.midsouthshooterssupply.com/s ... =18&GO.y=9

try this well lubed over 80 grains of black powder
Ive seen it used in several 50 caliber hawken replicas to take deer and hogs very effectively

NEI has several molds for 50 cal
you might consider a mini ball or maxi ball mold and a good deal of experimentation, several friends use those to good effect on deer ,hogs, and elk.
try to cast from fairly pure lead, don,t get crazy worrying about velocity , a 350grain-400 grain chunk of lead from a 50 cal can do amazingly nasty things to game if properly placed, and your 50 cal can easily kill elk, when properly loaded and accurately used
Ive found the 58-62 calibers a bit better in my experience but certainly the 50 cal is fully up to the job in the right hands, several of my friends prefer the 50 cal due to a bit less rifle weight and recoil.

Grumpy I just got my 1st muzzelloader do you put the cotton ball in then a dab of Murphys paste then your patched ball is the patched ball also lubed with soap? I bought pre lubed 50 cal. patches should I lube them with soap too? Is the soap a liquid or paste?

ONLY USE BLACK POWDER or powder SPECIFICALLY DESIGNED ONLY FOR MUZZLE LOADERS, modern smokeless powder use,can be disastrous
http://www.cva.com/Blackpowder-Videos.php?id=2#a

before you start,be 100% sure that you mark your ram-rod length with it inserted into a clean and unloaded barrel, then after you load the rifle and YOU are sure the powder,cotton ball and patch are fully seated in a firmly compressed stack ,in the breach, mark the ram rod a second time so you will know where it should be on a correctly loaded rifle with no air space over the loaded barrel, this also should alert you to a mistake made or double load or not completely seated load,as I'm fairly sure you realize having any air space between the powder charge and projectile can cause a serious pressure spike that can bulge your barrel, or permanently damaging it so you will need to fully seat any patched ball or mini ball, firmly over any powder charge,of the correct 2F black powder, in any black powder rifle you load.
OK, the use of the cotton ball and grease between the patched ball , and the powder charge compressed under it,will both increase velocity and noticeably reduce bore fouling as it both acts as a sabot and bore swab,with the rifles bore vertical, you pour the consistent volume of measured powder charge down the bore first, than thump the side of the barrel with your palm to hopefully causing the vast majority of the loose black powder to fall into the breach area of the rifles barrel.

the soap paste is similar to peanut butter or axle grease as it comes out of the can, wet a patch with water and rub a bit into both surfaces to get a well greased patch that makes loading a patched ball fairly easy
Ive generally found a charge of 80-90 grains of 2f to provide good accuracy with a 50 cal, patched ball.
you then place a decent size clean dry cotton ball in the bore and force it down bore about 1" a finger tip of the soap paste is placed into the bore on top,of the cotton ball, you want about a volume that will fill the bore to about a depth equal to its cross sectional area.
patchball.png


you then place a well greased patch that's centered over the bore ,and place the round lead ball in its center.
you then seat the ball into the rifling,forcing the ball diameter to seat and squeeze the surrounding patch into the rifling where in forms a cup like gasket around the base and sides of the projectile/,by placing the shourt started concave surface (A) on the projectile and giving it a firm shove with the short starter, now that its fully engaged , you flip the short starter and ram it the short length down the bore,
shtstA.jpg

this compacts the patched ball into the grease but forced the cotton ball below to act as both a bore swab and pressure gasket that prevents moisture from reaching the powder charge.

Grumpy where can you buy murphys flax paste I have been to a shitload of stores & looked on the internet & all I can find is liquid soap
 
I'm not sure if they make a paste anymore & if they do its as hard to find than an honest democrat
 
my local ace hardware used too sell it
I think this is the same stuff, unfortunately in a 8 lb 2 year supply size, but its cheap, it should be a paste about the color dark ginger-ale

a great deal of any rifles accuracy is dependent on maintaining absolute consistency in the pressure and velocity levels from shot to shot.
black powder leaves a lot to be desired as a propellant, simply because its filthy , it leaves about 20% of its mass as un-burnt ash, much of that,ash will build up, on the bore surface, shot after shot in layers on the bore surface, unless removed during subsequent reloading procedures.
to do this the rifles bore surface must be kept consistently free of fouling which is rather difficult too do with black powder as a propellant.
the truth here is that unless you can maintain a clean and consistent bore and rifling surfaces shot to shot using that black powder propellant, use of a solvent grease like the soap base grease keeps the bore surface ash from building up as a hard surface restricting and reducing the interior bore diameter, as this reduction and inconsistency,
will not allow decent accuracy, but simply wiping the bore clean with a solvent soaked patch , thats loaded so its separated from the compressed powder charge,that is compressed below it,by a cotton barrier wad patch, as each shot is loaded,
goes a long way toward maintaining that consistency.

Grumpy is there any difference in fouling issues between powders ? when I got my powder I got 2f equivalent from Hodgdon its called pyrodex RS-FFG equivalent haven't shot enough to know anything other than its a different experience & fun . A big problem around here is finding anything for reloading or muzzle loader shooting. No one carries anything another problem is I can't go to the range of the club I belong to I have to go to the farm where I hunt if I want to shoot in peace & the farm is a 2 hour drive. At the gun club I belong to you can't go shoot without anyone bothering you like the super hunter who kills a 48 point buck every year with an unloaded slingshot or the super shooter who hasn't missed a bullseye in 52 years with whatever gun or pistol he used
 
first I'm certainly not about to tell anyone Ive never missed while hunting, game, , in fact I've had some rather memorable screw ups I try hard to forget but a few old "friends" keep bringing up those "memories"
as to powders yes there's a fairly wide variation in the tendency to foul bores, and the bore diam. twist rate, rifling depth ,lead alloy, bullet lubricant and powder charge as well as the care taken in the machining of the rifling and the number of previous shouts fired the historic bore cleaning or lack of care during storage all play into accuracy
BTW Ive read several places that, long term tests were done,and if you carefully clean fairly new barrel rifling and spray the moly dry lube sprays into the barrels then swap the moly into the rifling at fairly frequent and consistent bore cleaning it tends to reduce bore wear. lead build-up and increase accuracy with cast bullets used

Ive always been into the older traditional muzzle loaders of the mountain man hawken type , mostly in 58-62 caliber
muzzle7.jpg

muzzle1.jpg

notice the inner edge of the muzzle rifle bores slightly beveled, this helps reduce any tendency for the rifling to cut the patch as it folds along the bore walls and projectile sides

BTW look very closely at the picture below its obvious the rifle land has machining chatter marks in the picture, these tend to degrade accuracy and trap and collect fouling

muzzle2.jpg

in these pictures the patches are NOT lubed
in actual use the powder will be poured into the bore first,
the barrel struck a couple times with the palm on the side to allow the powder to settle,
then a cosmetic cotton ball rammed firmly down on the powder charge,
then a soaking wet greasy patch with a firmly seated and correctly centered projectile will follow a thumb load of grease into the bore (the grease volume should be about equal to the projectile volume in size)
on ignition, the rapidly expanding gases slam the cotton wadding gasket against the grease and patched ball forming a far more efficient gas seal than the traditional greased patch & ball alone would produce plus the wadding and solvent grease loosened and scraped fouling from the rifle bore as it passed over in both directions

muzzle3.jpg

muzzle8.jpg

if you have any doubts as to the methods effectiveness simply skip use of the cotton ball and grease for 5 to 6 reloads and notice the difference in both accuracy and the resistance to the ball going down the bore during subsequent reloads

TIPS WORTH KNOWING
http://www.warrencustomoutdoor.com/mag-spark.html
BUY AND READ A DIXIE GUNWORKS CATALOG
http://www.dixiegunworks.com/product_info.php?products_id=17001&osCsid=3kenhmqmhosackgb4keaaaqou2

linen and denim are ideal patch materials, patches should be a bit over TWICE the projectile diameter I.E. a 50 cal will take a 1 1/8" circular patch a 58 cal will require a 1 3/8" patch
punches are available,
old-jeans_horiz.jpg

old jeans are a good source for patches

35-31closeup.jpg

fabric stores sell both denim and linen in several thickness weights by the yard
P8290006.jpg

http://www.jedediah-starr.com/closeup.asp?cid=90&pid=917&offset=0

patches soaked in ALCOHOL just prior to use and rubbed on both surfaces with the soap grease should slide with some resistance down the bore with a single firm stroke of the ram rod once started with a short starter in the bore , if theres excess resistance the patch is to thick or balls too large in diameter for the application it should be snug not super tight in the bore

THERE ARE MANY MANUFACTURERS OF ROUND BALL MOLDS

http://www.trackofthewolf.com/list/Item.aspx/1202/1
  • Lee
  • Lyman
  • RCBS
  • Saeco Bullet Casting
the heat you cast the balls at matters as the diameter they cool to will vary as a result, having a few molds and a cheap melted will save you a great deal of money in the long haul over buying already cast balls
http://www.midsouthshooterssupply.com/item/0000690009/Production-Pot-IV-110-Volt-
006-90009.jpg


the ALLOY will vary the molded Balls diameter, PURE lead is usually ideal, wheel weight alloy is usually too hard, for best accuracy, but testing will be required, you might be amazed at the difference if there is any.
the sprue or dimple that some molds leave on the cast ball is loaded facing strait up
