A slightly complicated question about revolver cylinder timing....

[Hokkmike]

I have a SA .45 Colt. (Uberti)

The primer strikes are dead on center when the gun is fired. The gun is pretty accurate. When loading or unloading out of the ports the cylinder must be turned just a little past the "click" where it stopped. Otherwise the bullets cannot be inserted into the chambers or the ejection rod will not be centered. it is relatively easy to do. I am assuming that a properly timed revolver means that the holes in the cylinder are lined up with the forcing cone and barrel when firing the weapon and the "off centered-ness" experienced when loading and unloading is normal.

Am I correct?

Correct. Usually you have to align the chamber a bit to eject empty cases.

If the cylinder locks up just as the hammer reaches full cock, then it is properly timed as far as the
hand or pawl is concerned.
If you can cock it very slowly and the cylinder does not lock up when the hammer reaches full cock, then the timing is slow.
If the cylinder locks up too soon and you can not fully cock the hammer then the timing is fast (very unlikely).

Colt SAA and clones and cap & ball SA revolvers let the cylinder bolt (lock) pop up just before the bolt reaches the cylinder locking notch for a particular chamber.
Ruger Blackhawks and Supers generally allow the bolt to pop up early, and so there is usually a drag line on the cylinder.

I have 2 Ubertis and don't recall any alignment issues for ejection. Do the checks Old Stumpy suggested. How far off is the chamber when you eject your empties?
The ejector rod doesn't need to be centered in the brass to eject it.
