Another thought is one shot zero. At a close range, get your rifle in a fixed device such as a gun vice or lead-sled and sucure your rifle as much as possible so it wont move.
Fire one shot and adjust your crosshairs to the hit, then you'll be right real close to zero with some fine "tunning".

EDIT: Two shot Zero, my bad
