Proper loads 4 an Olympia .50 cal. Muzzle loading rifle using pellets instead of powder.

put a cleaning pellet in the breech and discharge it outside into a sand pile or a 5 gallon bucket full of sand or water - if using water, keep the muzzle several feet away from the water, it can make a big splash and let water into the rifle in places where it would be difficult to remove.

Good afternoon Jay.

I found a couple .58 Cal Lyman Muzzle loaders for sale here:
Muzzleloading Rifles Modern Replica Percussion For Sale that were posted for $600. A H&A .22 rifle here
FALLING BLOCK 22 RIFLE was listing for $250 Wish I could get closer than that, but listings on H&A tend more toward shotguns and pistols, and have prices anywhere from $30 'wall guns' to $500+

Cheers

Most muzzle loading rifle have a "Patent Breech", and the "breech plug" threads into the back of the barrel.

"a round stuck in the barrel"



From that statement I assume you mean you had a bad load, and when fired the ball when only part way down the barrel and got stuck, correct?



If so, rather than unscrewing the "breech plug", you might want to try the less invasive old time method.



You might try a ".50 cal black powder bullet puller":

Attach it to the end of a cleaning rod, and screw the end into the ball.

The brass ring is non-marring in the steel bore.

Once screwed in good, pull it out!



Or, you might try a "CO2 bullet discharger":

Remove the nipple (if a percussion action), and shoot the blast of air through it, pushing out the bullet (have it pointed in a safe direction!)

A load for a 50 caliber rifle calls for 90 grains of FFG black powder or 90 grains of Pyrodex RS (maximum, start with a lighter load, and work your way to a good, accurate loading).

I'm not understanding the rest of your question.

Ok, I do not know of a manual for your gun. The main thing is learning to handle, load and shoot a muzzle loading gun. Here is a link to You Tube to see others firing similar guns. >> Here 460 grain Lyman conical bullet would be about 30 grains of black powder or FFg in Pyrodex. See load chart >> here > here

One thing about muzzle loaders, you should wipe or clean the bore after each shot. You need to find a method that works for you. I have an old CVA and I have to wipe the bore after each shot to keep it accurate, if shooting for fun I do not. But I would use my rod and with one patch in and out just to keep the fowling down.
Lets think of it this way. Even with the new powers they tend to build up. Now this build up causes each shot to have a different pressure and then each shot will run down the bore different. Hence one shot here another there.
Then there is the primer itself, The 209 primer has a very hot flame and can cause a bit of fouling.
See this link. Primers cause accuracy problems. It may help you understand what is going on. But the easy fix is to learn; wipe the bore after each shot. Use the same method to load powder, press the bullet in the bore, seat the bullet on the powder pellets, fire the gun, wipe the bore, start over doing the same steps, same motion, same pressure each time.

You load one pellet at a time when the barrel is broken open, the chamber is in the break of the barrel. One stroke, load, close, shoot, keeps you in shape. the old Sheridans, 10 pumps, really kept you in shape.

Whether or not air is coming out of the muzzle when you fire it tells you a lot.
