1000%, I vividly remember the Living History guy at the Trenton Barracks pointing to a chimney about 50 yards away and saying a soldier could not hit that with a smoothbore musketThat one is easy... if you look at all of the existing 1858 Remingtons with surviving boxes, some of which are paired sets, and some are highly engraved matched pairs..., you find all sorts of extra tools, and a cap box, and box of bullets...., but NEVER an extra cylinder.
What happens is what is known as information creep. An historian correctly points out something akin to, "The 1858 Remington had the ability for the user to change the cylinder, if a loaded spare was at hand, to swap out the cylinders, rather than reload each individual cylinder." THAT then morphs into, "Civil War soldiers carried extra cylinders to swap them out when reloading....."
Then add the ACW Living History community use during reenactment battles... keep reading...,
This one is likely more information creep. While they did issue out some SAA .45 Colts, they didn't issue the Rogers & Spencer revolvers. HOWEVER, a lot of officers carried their own personal weapons. So it's quite possible that a privately owned revolver in the hands of some officer, perhaps even converted to .44 Colt using a Richards-Mason conversion, which were part of the US Army inventory up to 1873, was seen being used. The conversion was of 1860 Army revolvers, so you get a poor observer who sees the guy is using an antique, not realizing it's a conversion... and says "Wow they are issuing Rogers & Spencer revolvers". Probably a "correspondent" screwed up. At that time newspapers would accept stories from "correspondents" that weren't even actual journalists.
This one is a reenactorism from at least the 1970's. The reenactors shoot only blanks, and so the powder when compressed might stay in the cylinder, but you don't want those chambers full of powder open when firing, so you cover the openings with grease. Most of the guys would compress nitrate paper over the powder to act as a barrier and hold the powder in, and then protect the paper with grease. They didn't know about poorly fitted caps back then. Then THAT transferred over to shooting live ball..., never understanding that the ball seals the front of the chamber and if you get a chain fire it was from the loose caps....
That's another hold over from ACW living history ; as I mentioned in the first part of this reply. Most of the umbrella organizations frowned on reloading revolvers during a battle, BUT since the 1858 Remington could swap cylinders, some guys favored those..., and you will find cylinder pouches used by some of them even though those likely are circa 1960... not 1860. Other guys simply went Josey Wales and carried a lot of Colt revolvers. Guys would point to photographs of enlisted infantry with lots of revolvers stuck in their belts (not knowing that such photos were staged). Since most Living History guys in the 1970's and 1980's didn't even know about nitrated cartridges, it was assumed that a guy with one revolver had to use flask and ball to reload in battle.... "since we would have to do that then they must've done that!".... gadzooks!
We get this too with AWI discussions of rifles and muskets. The guns were inaccurate, .... the guns were only good to 100 yards...they didn't practice marksmanship...., they closed their eyes when firing..... ., yadda yadda yadda, folks even today assume that since the tech is old, the accuracy must be "bad", when in fact the accuracy was OK to Good with smoothbore muskets, and very good to excellent with rifles, and continued to be so through the ACW. What changed over time was all weather capability and effective range..., that's all.
This is a fun discussion...
Years later here I am ventilating silhouette targets at 50 yards with a smoothbore musket
