Re: Ft lb of energy needed per lb of animal?
well , expansion and penitration are an issue that can't be overlookedas abullet kills from hydrostatic shock which is the energy that is transfered to the animal from the bullet. If your shooting a 300Wby with a 200gr solid bullet that doesen't expand at all that bullet is going to zip right through the animal without "dumping" any of it energy which would be alot , but if you shoot that same animal with say a 165gr Ballistic tip out of a 308 , that bullet is going to expand and "dump" more energy into the animal resulting in a quicker kill.
Now if you shoot that same critter with a 22-250 and a 50gr V-max at 4000fps then you probably won't get enough penitration to get into any viatals and kill the animal , yes you will have dumped all of the loads energy but not into the organs.
A bullet kills from either causing such an amout of trauma and shock that the animals organs shut down , or the bullet hits major bone structure and disrupts the centeral nervous system causing systamatic shutdown.
This is what makes controled expansion bullets best for hunting over no expanding solids , but is is possible to have a bullet expand to fast.
And remember Sierra Match Kings are terrible hunting bullets and are dtrictly for shooting at paper [img]images/icons/shocked.gif[/img]
