3rd-1000fps? I would love to know a bullet that works on game at 3000fps and still expands consistently at 1000fps. A-max has the lowest impact velocity that I know of which is around 1400fps(I could be wrong and it could be lower than I thought). Hitting an animal with a bullet that doesn't expand releases nearly zero amount of energy into the game and is like hitting them with a broadless arrow. Generally 2000fps is the rule of thumb for minimum impact velocity.

The minimum amount of ft. lbs needed on elk really does depends on the bullet. They are all different.
I agree with Theo on this one. While ft. lbs. are a consideration, the bullet IMHO is a greater factor. You can have two bullets that theoretically should deliver the same amount of energy based on weight and velocity and perform "completely" different on an animal. What happens inside the animal is what kills and ft lbs has less to do with it than other factors. That being said, a bullet delivering a very low amount of energy will normally not allow a bullet to perform up to its potential. Also, the elapsed time that a bullet takes to expend its energy inside an animal greatly affects the type and amount of damage caused even if the total energy expended is equal. This why a Berger and an accubond of the same wt. and velocity form different wound channels and could perform better or worse depending on the circumstances even though they both deliver equal energy. I don't mean to sound like the amount of energy delivered is of no value, but I do think it is often over rated. OK, I now have my flak jacket on...Rich
