The ballistic trajectory for 200 yards also passes through the same point at 50 yards. Essentially the trajectory arc passes through the same elevation on both ends of the trajectory.
The tip of the chevron would be your aim point for targets at 50 yards and 200 yards.
Because the bullet trajectory goes upward when it leaves the barrel before dropping back down, zeroing your rifle/sight at 50 yards will have the same bullet impact at 200 yards. That is what I zero all mine at regardless of barrel length, except for long range calibers (e.g., .308).
simply means if you hold on that point accuracy is good from 50 yds. to 200 yds. and anything in between those yardages.
That means your rifle zero SHOULD BE at 50yds OR 200yds. If you can get to a RANGE that has 50 yards, you can zero your rifle at that range. Bullets go up and then come back down, like a football thrown by a quarterback. Zero a rifle at 50yds, the bullet COMES BACK DOWN (due to gravity) at 200yds; hence the 50/200yd zero notation. Hope this helped.
