[QUOTE="Bart B, post: 1138756, member: 5302"] In response to my asking if the rifle stays still until the bullet's left the barrel.....If that's true: Why do double rifle barrel muzzle axes toe in several MOA to cross at 20 or so yards in front of them so bullets from each will hit point of aim 100 yards away? Why are handgun's front sight aiming reference higher above the bore axis than that of the rear sight? Why do rifle barrel's bore axis at the muzzle point somewhere else besides at a point above the downrange aiming point equal to sight height plus bullet drop? Typical .308 Win barrel times are around 1.5 millisecond or .0015 second; not .020 second as you suggest It appears that way, but if it were true, then the following would not be facts: [url=http://www.varmintal.com/amode.htm]Barrel Harmonics Mode Shape Movies[/url] [url=http://www.varmintal.com/atune.htm]Rifle Barrel Tuner Vibration Analysis[/url] It's been proved that us humans all see through rifle sights the same way. So, why do several people need a different zero to hit point of aim with the same rifle and ammo? I think you're forgetting about Newton's laws of motion. Of course, shooter's don't feel the rifle recoiling during barrel time because it moves only a few thousandths or hundredths of an inch. Its amount and direction is primarily determined by how powerful the load is, the rifle's weight and how far the bore axis is and its direction from the center of mass holding that barrel. [/QUOTE]
