Be aware that there is a smaller diameter " powder chamber " in the breechplug at the back( bottom) of the barrel. You will need to determine its diameter, and buy a separate cleaning jag, or bore brush, to fit in that chamber. You also will need to remove the clean-out screw from the side of the barrel, so you can inspect the flash channel. This is usually a pretty small hole from the base of the nipple, to the center of the barrel, behind the powder chamber. Polishing or even enlarging this hole some always aids in keeping this type of breechplug and flash channel cleaner. If you remove the plug , you lose the factory warranty. However, most of these guns will benefit from having that powder chamber enlarged. A .30 caliber bore brush will usually fit the chamber on a .45 barrel, but sometimes only a .22 or .25 caliber jag or brush will enter these chambers. I don't know anyway to learn what works, unless you can get this information from the factory, without trying different sized jags, or brushes to see what fits down there.
The flame from a percussion cap is HOT enough to make the right turn from the nipple into the flash channel, and then another right angle turn into the powder chamber. In fact, if you fire a cap off in the gun at night, without any powder or ball, and watch the muzzle, you will be amazed at how long a visible flame comes out the muzzle of the gun. You can't see this flame in bright sunlight. The good news is that the fire from the caps is USUALLY good and strong enough to burn out any debris, or residue left in the flash channel and powder chamber.
The Bad news is that WHEN IT DOESN'T, you have a huge problem clearing the gun barrel, and then cleaning the flash channel and powder chamber before you can reload the gun.
I suspect that the name on the gun is that of a prior owner. He is probably the one that added the inlays to the stock. Can the owners of the store where you bought the gun tell you anything about who sold them the gun? That would be how I would try to locate and identify this person.
