I fired my Uberti 1858 Remington revolver today, I used to have an EMF version back in the 1990's and they are a little different. The Uberti is tighter in removing the cylinder, had to relearn the method to partially cock the hammer and wiggle the cylinder and hammer to put it back into the frame. My EMF was not so tight. My Uberti is much more accurate than the EMF, the Uberti is one of the most accurate handguns I own.
The main problem I had was what seems to be a sticking cap in the top of the frame. On my Colts I just rock the gun upright when cocking to allow the spent cap to fall out. On the Remington this is not an option. Should I pinch the caps on tight to prevent it from sticking in the frame and cylinder area after detonation? The first few shots are ok, then it was sticking so back that I had to manually turn the cylinder with my other hand on several occasions. I thought it was powder fowling, but I cleaned the gun after 3 full cylinder loads like I do with my Colts.
The gun shot right to the point of aim, quite a contrast to my 1851 Colt which shoots high and the the left.
