in theory a 110grn hp from 30/06 delivers more energy than a 180 grn...but delivery in a 1" deep dinnerplate sized crater doesnt kill well.....a 1" wide 12" deep hole kills very well.

the difference there how much resistance there is to the projectile. If the bullet can deliver all the energy then it would move the box a lot.
Ultimately though if you fire the gun and cant knock you over then the bullet cant either. Equal and opposite reactions and all that
