I have never killed an elk either, but hunted for them once, they are huge and I was half a mile down an extremely steep ravine when I had the chance to squeeze off on one. Had no horse, just a four wheeler and decided that was a haul I was unprepared for, so I suggest you be physically and mentally prepared for the sometimes daunting task of getting one out. I had always been told the same thing, and was in good physical condition but when I saw one I was shocked at the size. I hunted a different area for the rest of the trip where I saw more elk, but did not get a reasonable shot due to brush and thickets where I saw them. The bulls will blast through the middle of tree tops and not stop or jump, they just tear them down, and you can hear them coming from a mile away. As far as shot placement goes, from my understanding, shot placement is everything on an elk when shooting anything less than a howitzer. It is my belief that if you fire one well placed bullet of strong composition then you can kill an elk with your .257. but be ready to fire more. Just make sure you choose a stout bullet. the accubond, interbond, GMX, partitions, and X bullets of whatever variety should be sufficient for penetration and proper expansion. I would however TRY to avoid a direct shoulder shot. If you want to shoot cheaper bullets you would need a bigger gun. When I went, I carried a .300 win mag with 190 gr. Interlocks, and a 6.5x55 with 130 grain TSX for places where the shots would be a little closer and more hiking with my gun was necessary. I put a 400 yard limit on the 300 and a 250 yard limit on the 6.5x55, just as a guideline. 400 because I was not positive of my ability beyond that and 250 for the small gun because I wanted to make sure I had well above minimum energy at the point of impact. Be disciplined with your shot and you should be ok. if you are someone that sees a critter and just starts firing rounds down range without thinking then you would do well to practice a lot on both your shooting and your ranging capability. you won't always have time to use a range finder.
