Case setback is when the brass backs out of the chamber, often tying up the gun. The best example is the S&W M-53, shooters found the 22 Jet backed out regularly. The problem there was the round was too high pressure, without a bolt face to hold the rim in place, the tapered case did not grip the cylinders walls properly. It seems the lower pressures and more gradual case taper of the 44-40 do not cause that.
