[QUOTE="Long Time Long Ranger, post: 501292, member: 505"] In extreme range hunting your bullet is dropping through the kill zone of your target for a very short distance. It is best to choose a cartridge and a bullet that will have you in that kill zone for the maximum range to give you a better opportunity for a kill. That bullet needs to be one that will give you the best opportunity for a kill. The largest caliber heaviest bullet you can keep in the kill zone for the longest distance and be able to shoot it accurately from a shoulder fired weapon that is light enough to carry hunting with you is best. When punching paper or shooting rocks at extreme range you can walk it in to the target and then pepper it with about anything that is accurate. Hunting is different and you need a rifle that will give you the best opportunity with the first shot. Using my data above at 1200 yards the medium size 338's pass through a 15" elk size kill zone for 18 yards. Assuming your rifle shoots a ten inch group at that distance which averages out velocity spread you are in the kill zone for 12 yards with every bullet. With a big 338 like I use long range you are in the kill zone for 23 1/2 yards or 15 1/2 yards with every bullet from a ten inch group. That gives you a 23% better chance at getting your elk first shot. Actually more when you consider the 9" less wind drift. When choosing a long range rig know how to analyze ballistics data and pick a load for your rifle that puts you in the kill zone for the longest period of time while not letting windage get out of hand. There is a balance and the least wind drift may or may not be the best answer. You may find a load that the wind drift difference is negligible when compared to how much longer you stay in the kill zone vertically as you drop through it. [/QUOTE]
