This is purely my observation, but a Ruger cylinder will burst with an excessive handload just as with any other manufacturer's cylinder of the same dimensions. If not burst, at least bulge.
To say that Rugers are built "like a tank" is true, but that strength is in the frame and overall make up of the gun. That is, it is built to absord the stess of recoil forces. Part of the strength is its thick top strap. I have seen a Ruger digest hundreds of heavy loads when a similar single action suffered a very pronounced stretched top strap.
There is no practical advantage to going "over the top."
