Differences in the bores between rifles can account for some people seeing high pressure and others not.
Higher friction that a bullet encounters going down the bore causes higher pressures in the chamber. When you coat your bullets with a friction reducing compound you typically have to increase your powder charge several percent to get back to the same muzzle velocity you had before coating because of the lower pressure that results from the reduced bullet friction.
