I see posts on ML rifle accuracy and wonder how it relates to accuracy back in the day. Of course we want a rifle to shoot a MOA, but in my limited experience, I think this is a false goal. Except in VERY limited and exceptional rifles. Like match BP rifles. I also feel that MOA isn't either necessary or should be expected in ordinary ML rifles. Three MOA or less is to me acceptable. That's just me. I doubt many deer back then were shot at 100 yards and squirrels or other small game were shot at 15 yards or so to save powder and ball.

I don't have any ML rifles that will shoot anywhere near MOA. My .32 will hit a paper plate at 100 yards and I'm happy with that since I don't intend to to shoot anything at near that range with that range. It has accounted for a number of squirrels at reasonable range.

So I feel claims to shoot a lot better than three MOA (or so) with ML rifles especially with period rifles are grossly mis-represented. Considering that our ancestors had powder of dubious quality and erratic patching material, I think it's a myth, but considering the accuracy standards of the day, we Americans were definitely superior marksmen...just not like today's marksmen.

It kinda all depends on what you as a shooter are after. If you are just shooting at swinging metal targets, all you need is to be able to hit them.

Some people are content with 3 MOA, while others try to get sub MOA with a rifle. All depends on the person and what they are expecting out of a rifle.

Neither are wrong, just personal expectations.

Minute of angle for a three shot group at 100 yards is doable from a bench with a round ball rifle larger than .32 caliber, not sure about .40 caliber, but definitely with a .45 or larger round ball rifle. It does take some work to find the correct powder charge and type of powder, ball, patch and lubricant the rifle likes.

It also takes some training and discipline to learn to shoot that well. Yes, I have seen it done at International Muzzle Loading Shooting competition with original rifles at the 100m prone and this from Ladies shooting. The groups will open up after three shots and especially when shooting 10 shots or more, but much of that is from Shooter Error rather than what the rifle is capable of doing.

Shooting competitions in the 18th century were often done with only one shot and often at around 60 yards, so we don't have much information on how well they shot groups. Spence had a quote from one of the best Hunters in Kentucky in 1820 and most likely a flintlock rifle and not a match rifle. That hunter bet people he could hit a silver dollar (around 2 1/2" diameter then as now) and the winner would get a dollar each time he did it. The person did not bet, but others said the hunter was able to do it on almost every shot. The quote did not say if the Hunter used a rest and he may well have or even probably did so or shot from prone.

I grew up hunting mainly with a shotgun, though some .22 rifle shooting and .22 pistol for raccoon hunting. Because .22 ammo was cheap, I got quite good at hitting upright soda pop bottles offhand at 25 yards and breaking them into three pieces with follow up shots; hitting the tops first, then in the middle, then at the bottoms. However, I never fired a large caliber rifle until I entered Marine Boot Camp six days after my 18th birthday.

In Boot Camp, we had what was called "Snapping In Week" that was some of the most intensive and body aching work at getting into the tightest positions possible, so we would shoot our best the next week for initial qualification with the rifle. I was in fairly good shape before I went to Boot Camp, but that training cause a lot of body ache each night. However, it allowed us to shoot really well the next week.

Six days before I graduated Boot Camp and came home on Boot Camp leave, I came down with walking pneumonia. Yet, I recovered well enough to come home on time to Iowa in January. I purchased a TC .50 caliber "Hawken" Rifle and the accessory kit. Grandpa helped me cast balls from the mold in the kit and I used the patch and lube in the kit. I bought Dupont powder. I just HAD to shoot that rifle before I went back from leave as I had dreamed of owning a muzzle loader for years.

We did not belong to the only range anywhere in the county, so we went to a public recreational area when it was 10 degrees above Zero with intermittent icy winds. We measured 100 yards using a tape measure and set up a paper target. I brushed snow off the frozen ground and sat down to take up the best sitting position possible. I thought about trying prone, but just could not get myself to actually lay down on that frozen ground. Grandpa was the last person in our family to have fired a muzzle loader, but he had done it as a boy. So Dad and I had never done it.

I used the suggested charge of 60 grains of black powder. Young eyes, superior marksmanship training and the natural accuracy of that rifle allowed me to shoot a three shot group where the furthest distance between two shots was between 1 5/8 and 1 3/4 inch. I could not measure more accurately as it was so cold and my hands were shaking after I had loaded and fired three times. In better weather and once I found the most accurate load for that rifle, it was capable of shooting three round 1 1/2 inch groups at 100 yards all day long from the bench. Of course I could not hold that tight of group offhand, but from sitting and especially prone, it was quite common.

Now, I was never good enough to shoot on any of the Rifle Teams in the Marine Corps, because of the astigmatism in my eyes. I was also never good enough to get into the top five of any of the primitive matches I shot at Spring and Fall shoots at Friendship, IN in the last half of the 1970's.

Still that TC Hawken Rifle would shoot BETTER than I was capable of shooting at 100 yards and I was able to shoot 1 1/2 inch three round groups with it.

I'm convinced that the accuracy of a muzzleloader at 100 yards is only limited because of the shooter. These primitive sights make it a challenge, especially for we seniors. I know my eyes are nothing like they were 20 years ago. I believe most muzzleloaders have the precision to shoot 1" three shot groups and 5 shots well under 2". The only rifles I've fired at 100 yards (at a target) were a .50. .45 and a .40. Most groups were around 4" with a couple exceptional groups, for me, of about 3.75". Those were very good days since most of the time I do well to keep 5 shots on a dinner plate at that distance. Three shot groups are generally smaller.

I've always done well shooting from a bench; but that was with suppository rifles. I shoot better with a muzzleloader standing & braced against a post or tree; Field positions work for me too.

One day at a friend's house we were shooting my .36 SMR at well over 80 yards. With 20 grains of 3F I had little trouble hitting plastic coke bottles; the only trouble was seeing the darn things. I've had pretty good luck shooting tiny groups at 50 yards on good days, but anything beyond is a manure-shoot.

Very much agree!

There is a lot of mythological stuff floating around about muzzleloader accuracy back in the day.

i've owned numerous muzzleloaders that were made in the 1800s, including a real sure nuff Hawken. A few of the bores were in really good shape: Every one of those nice bores had inclusions in the iron.

You could run a patched ball down the long barrel and find loose and tight spots. Only one of the original guns i owned shot really well. It had been re-bored and re-rifled by Hacker Martin in the early 1930s.

Back in the day lots of folks had bad eyes. Glasses were not readily available. Folks with bad eyes do not shoot well.

i was the senior firing range advisor to the Saudis for years. Many Saudi troops could not shoot well; mostly attributable to bad eyes. There is a devastating eye disease there called trachoma. And it ain't manly to wear glasses.

One unit, a remnant of a princes private army, forced troops with bad eyes to wear glasses. They were outstanding marksmen.

Another thing. Not all the game animals those old time hunters shot died right away. Some were tracked for miles after shooting. In my Great Grand Dads diary there is an account of his shooting a deer with a muzzleloader. The deer took off wounded. Grand Dad finally killed that deer on the third day.

i have not shot a 1" three shot group with a conventional muzzleloader in decades; nor do i care. i do kill a lot of wild hogs.
 
Ooh Rah!

Apart from sights, (which affect mostly the nut behind the butt) ML're suffer from several handicaps compared to suppository rifles;

# 1 is lock time. Even the fastest of cap guns are going to take about 3x longer to get the bullet out the bore than even a pretty good modern rifle.

# 2 is the patch / lube / ball / conical situation. Gilded bullets are swaged by the high pressure powder blast to fit in to the lands and grooves really tightly. ML'ers can't withstand that sort of pressure to get that tight of fit, though at least SOME bullet obduration DOES occur. In addition to that, even the most careful patch fitting at the muzzle is still going to yield at least some variation between rounds, as will powder compaction pressure with the RR, thus affecting the pressure curve.

# 3 is barrel length. The longer and more flexible the barrel, the greater the tendency to oscillate, and greater the amplitude of them. If EVERY charge resulted in identical pressure curves AND barrel dwell time, AND muzzle velocities, and barrel temperatures (dictating metal flexibility) then the rounds would hit in the same place every time. But they don't. A shorter stiffer barrel will mitigate some of that (which is why target .22 shooters use 19" rifled bores, covered by a barrel extension for extending the sight radius), but with the BP burning curve as it is, such a short barrel would also not yield very good velocities with the amount of powder that could be efficiently consumed in such a short space.

There are probably other factors as well, such as atmospherics / variations in wind, as well as the relatively slow velocities and inefficient ballistic coefficients that are additional contributory factors to the variations in flight time of a string of RB's vs. that of a string from a more efficient shape.

Maybe there is other stuff out there I've missed, but this is what I can come up with for starters.
 
My principal hunting pard has a couple of sets of scope bases from TC designed for their Hawken barrels. Picked them up at a garage sale NIB.

Out of curiosity he and I both have shot his assorted TC barrels with and without scopes. Don't recall a single one that would shoot an inch at 100 yards from a solid rest with its best load AND a modern 4x12x scope. About the best average any of them can manage is 2" @ 12x.

The interesting part came in benching those same barrels and best loads at 100 yards with factory sights and again with TC receiver sights. Most likely a measure of our geezerly eyes. The factory sights never beat 4" and the TC receiver sights split the difference at 3".

Way we read it, a 1" drop in group size ain't worth the weight, hassle and expense of a scope when the tang sights are so cheap and easy. Of course, read a little further into our thinking and a guy has to ask himself if the change to tang sights and a 1" change is worth the expense and effort.

We've mostly decided the tangs are worth it. Not for the 1" drop in group size, but for better sight visibility on hunts.
 
:metoo: What can you see and what can you hold on. A silver dollar at sixty yards is smaller then my front sight. We use tricks today to know when we are on center. Our black spot on a traget is pretty good sized. So, we are holding on the black spot not on the center x.
Since deer don't have targets on them we have to hold on landmarks that in irregular light don't give us the best sight picture. Should you be able to hit a dinner plate at a given range and you hold on Bambi's chest you have deer for dinner.
Should someone hang a scope or a peep sight on their gun its ok with me. I have not needed it yet, might need it tomorrow.
As too old boys that could shoot a flies eye at 300 yards I just don't believe they were any better at seeing flies eyes then then we are today.
 
This is my group at 100 yard with a .54 cal lyman GPR, a lyman 57 peep sight, and dutch shoultz's system applied. I have the set trigger setup for hunting, so their about as heavy as it can be before the trigger doesn't operate at all.

90grs FFFg goex, weighted hornady .530" balls, dixons green stripped pillow ticking with ballistol and water combo on patch and dried. Shoultz's moose milk formula and a patch between shots. I believe I use 3f in the pan that day too.



Not sure if photobucket likes me or not......

This is from the bench, the 1st shot is high. The rest are touching. That is my hunting gun, so it's set for the 1st clean shot.

Without the peep, 2" groups at 100 is about it for me. I have 2 very good shooting modern arms with the same peep sight and front sight combo. Both shot 2" or so with just the irons, then got groups like shown when the peep sight was installed. The peeps aren't targets either. I drill out the aperture to .110". I clean and dry the front sight with alcohol to keep oil from creating glare. Polished brass is great on dreary wooded lots, but horrible for sunny day range trips...

Doing a 6 o'clock hold helps a ton too. The right color background coupled with the right size shape and color target. I almost always make my own targets and normally use either cardboard or manila paper.

of course, big balls help make cloverleafs happen too........

I had to relearn how to shoot a gun when I went to blackpowder with set triggers, which I hate. The better the aim, the more a I squeeze. I like a 4lb pull that takes about 1/8" to 3/16" of travel to get there. Some creep I can work with too...
 
Well by 1867 this was expected by at least one expert in the field of muzzle loading rifles shooting patched, round ball...,

200 yards may be taken as the very outside limit at which it is ever advisable to fire at ordinary game; not because the rifle may not be accurate enough to ensure frequent hitting at much greater distances, but because the probability of killing at such ranges is very small indeed;

Moreover, most men who have shot much in the forests of India will agree that it is only on the open plain that such long shots present themselves. In the jungle, at lest one-half
[of the shots taken] are under 50 yards, three-fourths are under 75, and all, with scarcely an exception, under 100; that is to say, these are the distances at which animals are usually killed in jungle shooting, and I imagine that the case is very much the same in other forest countries.
James Forsyth The Sporting Rifle and Its Projectiles 1867


My experience bears this out, as do many of the accounts of fellow hunters using traditional muzzle loaders. As long as the area where you aim at the animal's vitals or shoulder will be hit with the rifle's load..., being able to place the shot within a 6" ring, or into a clover-leaf pattern at 100 yards is a moot point I think to the slain animal.

I have on my desk three round balls stacked up. they were shot at 60 yds. muzzle rest. h & a .45 under hammer. original open sights.i have a .40 that I have stacked up balls at 75 yds. more then once.

I picked up a GREAT trick with targets at Clark Brothers Sporting Goods Store and Gun Range in Warrenton, VA MANY years ago, that I still use for shooting smaller groups AND for sighting in for hunting.

Put a One Inch Round or Square WHITE "stick on" Dot in the center of your black bullseye targets and aim at that for a MUCH finer aiming point. Doesn't matter if you use a six o'clock hold or point of aim/point of impact hold, because that Dot is so small. The contrast of the White Dot REALLY stands out on the black bullseye background. BTW, I have also tried orange, green, red and other colored dots in the center and they don't work nearly as well as the white dots.

Now, when sighting in on the One Inch Dot, that will put your rifle ball on any spot on the deer you want to aim. IOW, you don't have to look for the deer with the bullseyes on their hides.

A handy trick, I've been doing that for a long time, and it works.

I frequently make custom targets for a specific job, and that makes it easier for me to get a gun set up. For example, I have my plains rifle shooting small enough groups, and windage is no problem, but I still need to file the front sight to raise the POI to where I want it. Using plain typing paper I made a simple sighting target with lines at the proper distance above POA, 1" at 25, 2" at 50. The heavy, sighting bar, is easily visible at 25 and 50 yards, and I don't need to see the proper elevation lines until after I shoot. I find these special purpose targets quite handy, and they make interpreting my results dead easy.

My muzzleloader accuracy standard is: "Minute of Grapefruit". I have several rifles, .50 and .54 cal, flint and percussion, all capable of exploding grapefruit at 100 yards.

If I want sub-moa & at longer ranges, I have the proper gear for the job, too.
