[QUOTE="Bright Raven, post: 1431348, member: 27490"] When discussing trajectory, the path a projectile follows is influenced by a number of forces. Gravity, wind, atmospheric conditions, resistance, etc. As soon as the primer detonates, the forces on the bullet are initiated. In regard to barrel life, replacing a barrel is a small price to pay for performance. Throat and barrel erosion became an issue in the 1950s with the wildcat cartridges of yesteryear - 220 Swift, etc. Who cares if you are a sniper or a long range professional. Not only are the forces an issue but there are other limitations. Don't for get the distortion of optics. Warren Page who wrote for Field & Stream coined the phrase "shooting through the swimming pool". If you have ever looked down at your arm when standing in water, you will note the displacement caused by a liquid medium. Atmosphere causes the same distortion. Bench rest shooters commonly refer to distortion and "mirage". I don't have time to deal with this subject as I would like. So let me open this to Viva, Joe, dun, etc. I particularly want dun to participate because he is probably dated on his long range shooting as I am. Here is what I would like to explore: is shooting at this range feasible? Why do I ask? Because the forces acting on projectiles and the limitations of optics in my opinion make shots like this a fluke. It is stated as a record. The variables between shots on a target at 2.2 miles are too extreme to make shots at that range repeatable. Think about this: at that range even minor changes in the circulation of land air currents will move the projectile not inches but feet. Mirage and optical distortion will vary not inches but feet between shots. I agree with the concept of "walking in" but even then, the variables between shots would be frustrating. I want someone to convince me that the trajectory of a projectile fired using rifled barrels and centerfire ammunition, can be precise enough at 2.2 miles to be anything but a fluke. [/QUOTE]
