On a bolt action rifle you only need to push the shoulder back .001 to .002 when full length resizing.
A full length resizing die is designed to push the shoulder back .002 shorter than minimum headspace. If your actual headspace is .003 more than minimum headspace and you die is set up to make hard contact with the shell holder you will be pushing the shoulder back .005 or more. This will cause case head separations and short case life and could als effect accuracy.
Below simple ways to control and measure cartridge headspace.
