I just have to get my oar wet on this; it seems to me some people always miss the point. The idea is to match the bullet and its performance to the animal. Putting foot pounds into the hill behind the animal does not bring it down faster.
I have shot quite a number of animals between 100 and 300 pounds with a gold Dot 250 it always came out the far side of the chest it always dropped the deer or boar right on the spot. This indicates to me that it is the right bullet for that weight of thin skinned animal. Sure there are some others that will take them down as good. And it does not mean I use the 250gr on elk, moose or big bear, the 300gr Gold Dot or Lehigh would be much more appropriate which is what I would go to right now, but I am also looking at a 325 and a 350 gr bullet that I might work up. Most bullets will do some kind of a job at the appropriate velocity and I am inclined to believe that most so called bullet failures are really failures to use the right bullet or the right velocity.
This is mainly for the newer people. Think about why the bullets that penetrate the deepest are outlawed. I case there's doubt in your mind its is for two reasons. So that the game is retrievable and so you don't have a bullet flying wildly across what ever area you are hunting in. { full metal jacket and armor piercing are bad about bouncing around.
