Referring to the citations in Dr Drews comment , I did not find the increase he stated. I did find the statement that the increase for shooting a 23/4 cartridge in a 21/2 chamber would be less than 1000psi. Another Sherman Bell DGJ article says 3 to 5 percent. For a 10,000 psi load, that is 300 to 500 psi.
