2 laws:
1 A body in motion tends to stay in motion unless acted upon by an outside force.
3 For every action, there is an equal and opposite reaction.
(the other one is the one that gets the most traction in physics is F=ma; if you are good, you can derive most other mass/speed/distance equations from this one - I just couldn't think of how to apply it here).
Anyhow, 1) the .177 pellet is staying in motion and not transfering much of its energy because of too little resistance in the starling.
3) If the starling were a steel plate, all of the energy of the .177 would be transferred to it.
So we are trying to transfer more energy to the starling without the ability to change its density so it can absorb more. Bigger surface area is the key: .22 is obvious. Wadcutter is as big as you can get for a given caliber. Hollow point makes a bigger surface area when it hits. Heavier/slower gets more time to transfer the energy as it passes through. The combination of heavier and hollow point transfers the most energy with the gun he has. Ergo sir knight: Crow Magnums. |
