[QUOTE="MontanaRifleman, post: 367351, member: 11717"] Another thing to consdier is which zero are you talking about @ 100 yds? Bullets almost always have two zeroe points. The first zero point is usually closer than 100 yds and it's where the bullet's trajectory passes throught the scope's line of sight on the way up in it's initial path out of the bore. The bullet then crests and begins to drop to it's second zero point when it crosses the scope's line of sight again. With a 243's trajectory, the two zero points may both be close to 100 yds. They might be 100 and 110 yds or 90 and 100 yds. When zeroed at 200 yds the first zero will be between 25 and 50 yds because it requires a steeper trajectory to get the bullet to zero at 200 yds. The answer to your question, when you change your zero, you change the trajectory and you can't compensate by doing straight math. One reason is, the bullet drops quicker, the farther down range it gets. -Mark [/QUOTE]
