[QUOTE="Shawn Carlock, post: 165585, member: 4"] Robbor, This a subject with alot of different opinions from alot of different people based on alot of different things. Here is my $.02. For me there are just a few issues: 1. Energy is a usless figure in my opinion to many variables. Bullet performance at a given speed is my concern. 2. First and foremost I must have at least a certain amount of penetration for a given animal. This can become a varied issue. If my bullet expends all of its energy in an animal it does not exit leaving no exit wound. This is a devastating effect in a classic broadside heart lung hit soft tissue hit. No exit wound can make recovery tough and that is a consideration. Also at this limited penetration level slight windage errors, angled shots and other factors can cause bone hits or other long penetration needs. In this respect the bullet or bullet pieces may not reach the vitals and will have failed you. If you think you will always wait for a broadside shot and always place the bullet in the soft tissues heart lung area and never screw up the windage your kidding yourself. To this respect I prefer a bullet to be able to penetrate the shoulder bone masses and into the vitals of the biggest animal I might hunt. I actually prefer a point on high shoulder shot for instant "smokin fur". However I cannot always count on hitting that small zone and have to allow that I might be off in windage a little resulting in a soft tissue hit. This penetrating round must expand some while passing through for the best effects. It has been my experience that if it doesn't expand at all the animal is still just as dead and just as quick but with little to no blood trail recovery in some types of country can be difficult at best. In summary I look at this: 1. Will my bullet / impact speed combo pass through heavy bone into the vitals? 2. If I make a soft tissue hit will it expand enough to leave a good exit wound. This is really nice but not manditory. 3. I always error towards the side of over penetration 4. I test penetration in varoius way to determine effective distance before using a combo in the field to take game with.
