[QUOTE="ShtrRdy, post: 1720141, member: 40852"] There has been quite a big of discussion on this topic over on the Snipers Hide forum. The consensus is that the difference in zero is so small that it basically doesn't matter when you zero the rifle system at 100 yds. One way to think about it is like this: 1. The bullet begins to drop as soon as it leaves the barrel. Gravity starts pulling it downward at the rate of 32.2 feet per second every second. But the barrel is inclined upward. 2. When you zero the rifle at 100 yards the bullet rises from the elevation of the muzzle and "touches" the line of sight, (from the scope), before it continues dropping. 3. The Time of Flight between the firing position to the target when shooting over 100 yards , is so short that Gravity hasn't caused the bullet to drop too fast YET. (about 0.11 second) In the ballistic program your using do you have a separate group of entry boxes that allows you go enter Zero Atmosphere numbers? In the program I use those boxes are located in the ammunition entry page. [/QUOTE]
