Huh?CraigC said:There is no such backthrust in a percussion gun.
Explain, please. How does the ignition system affect the recoil load paths?

Thought we were talking about the 44 caliber, 1858?Straw Hat,
Some claim Remington did offer the '63 .31 in brass based on old ads from the time.

Not sure what that means. Could be wrong, but I interpret it to say that you believe a percussion cylinder only bears on the arbor. That's not the case; it impacts the recoil shield all around the arbor. The arbor itself reacts the moment created by the off-axis bullet motion in the Colt design, whereas the Remington top strap takes this force in compression. Not sure how that compressive load results in frame stretching.A percussion cylinder does not bear against the recoil shield above the arbor/basepin but only at that point.
StrawHat said:Remington never produced a brass framed revolver. Only the copies were produced with brass frames.
I'm saying that in a cartridge gun, the case head itself bears directly, straight back against the recoil shield at the firing pin. Due to headspacing, it also gets a tiny running start. It is this backthrust, as proven scientific fact, that causes frame stretching. In a percussion gun, there are no cartridges to backthrust against the recoil shield, nor are the forces it does endure so high on the frame, resulting in increased leverage. The forces are more of an indirect twisting action against the arbor. Those are two very different forces bearing against the frame. IMHO, it is very simplistic to say that the Remington is stronger than the Colt design because it has a top strap, when you do not take into account the forces encountered or their design intent.Not sure what that means.

William Mason designed the Colt SAA with a top strap because the Army asked for it. Only months prior, they would've been more than happy to supply them with the 1871-1872 Open Top .44 rimfire....when the management and designers employed by Colt Firearms created and marketed the Colt 1873 Single Action revolver for the blackpowder cartridge round they must of thought the top strap was necessary for the strength and durability of the revolver.
I'm not familiar with this proven scientific fact. I am familiar with the science of engineering statics and free body diagrams, and I'm unable to create a diagram that results in the frame stretching you claim. Perhaps you could refer me to the source of those scientific facts or provide the free body diagram.CraigC said:It is this backthrust, as proven scientific fact, that causes frame stretching.
