Stay away from " Maximum loads" in these replicas. Although they are made with better steel, they are still old designs, and the parts in the action can't take continuous pounding of " Maximum " loads for long without wearing down, breaking, or getting very lose. Want to shoot maximum loads? Get a modern Magnum pistol.
Most .36 caliber revolvers shoot fairly well with as little as 15 grains. Don't exceed 20 grains, for safety, and longevity. Now, understand, the companies, and some dealers want you to abuse your gun, so you have to buy another in a couple of years, or sooner. That is how they make money. The question is, do you want to have a nicely made gun that you can shoot for years to come, and pass on to your grandchildren in good enough working order that he or she can shoot it for his lifetime?
With the lighter loads, you may have to use a filler to make up the space difference in each chamber between the powder and the ball, which you want to keep out at the mouth of the chamber, to lessen the jump it has to make going from the cylinder, to the barrel. Reloading cap and ball revolvers is not a speed shooting event. It takes time, and you want to do it correctly to get any accuracy out of the gun. You may have to do a little cleaning with each reload, too. I suppose if you can buy extra cylinders fitted to your gun when you buy it new, then you can try to do the Clint Eastwood stunt as shown in High Plains Drifter. But remember, he was shooting blanks, not real lead ball. The guns get a lot dirtier shooting live ammo, and I have had guns get so dirty that they were locking up by the third cylinder if I didn't do a little cleaning when I reloaded the gun. In the civil War, they did not reload these guns. They often carried more than two revolvers, carrying the extras in scabbards hung over the saddle horns. The Outlaw Josey Wales is probably a better depiction of how these guns were used by horse soldiers, if you are getting your firearms history from the movies. The only thing that was a stretch of the imagination was that the Eastwood character, did not carry or use a sword in battle, and didn't even have one in a scabbard on his saddle. You don't have to reload a sword.
