I will refer back to a thread I submitted last fall "long range elk mistake". I have a 6.5 Sherman which easily out performs the 6.5/284. I am a big proponent of the 6.5 cartridge and always will be for that matter. The problem with trying to kill elk with ANY 6.5 at 1000 yards is twofold. Trying to get a bullet to expand at that velocity is not at all consistent (regardless of advertised). Also, the frontal diameter of the bullet which isn't much to begin with, coupled with fairly low energy, does not make for a consistent elk killer. Yes it will kill elk, and you may get three or four good kills before one runs off, but are those the odds we want? Hitting the animal is not a problem and neither is penetration, but an elk is a tough animal. I have killed over 30 bulls and from now on, I will take my 30 with bullets that expand at that distance. IMO....Rich
