Only if the oversized bullets will fit inside a fired case from your rifle.
According to Ackley, if the chamber's neck allows enough expansion to release the oversized bullets, there will be zero or very little increased pressures, according to his tests with shooting up to .35*" bullets from a .30/06. He had to increase the neck diameter of the chamber to allow the shooting of the 150gr. .358 bullets. The same powder charge was used for all bullet diameters tested.
