The 1858 Remington-Beals revolver was accepted during a time when the military issued nitrate paper cartridges loaded with light 17-24 grain charges of "pistol powder " and a heavy conical . The idea was to mitigate fouling so the guns could get through an 18 round "issue" of ammunition. And both the Colt and Remington had no problems functioning under what the Ordnance Dept thought was expected combat use.
both will foul up with extended shooting, which is why letters home from soldiers talk about pouring canteens over revolvers to free them up in a fight, so they could be loaded again. Because plenty of guys carried more than the 18 rounds allotted as a "standard" by the Ordnance Dept
So, here in 2022 people dump 40 grains of 2f, 3f, 777,or Pyrodex , or whatever into the chambers of Rems and Colts, using various lube. Or not. Lead round balls, sometimes cast from harder alloys and we get the "information creep" of how these guns perform vs each other based on range blasting and field use with charges and projectiles the guns were never designed to use and Italian reproductions are just that, reproductions that are pretty close to originals but not the same
I just think it's funny that people will vehemently stand behind a weapons design because they own an Italian repro of it, this is what makes the shooting hobby so awesome.
