As your cartridge head spaces off the shoulder or belt it will not impact the jump to the lands.

As long as your primer is seater in as far as it will go all is good. While flush is ideal a few slightly proud is no real issue in my option.

Personally I am not keen to try your suggestion.I am so anal about safety I dont even buy factory ammo.
