Re: 5.56x45 Trajectory Question
I've always read it should be very close at 300. However I prefer the 50/200 yd zero. I have used it with great success out to 200 yards with xm193 ammo. Pretty much dead on at both ranges.

25/300-325 Depends on if you are Army or Air Force. An M16A2 is zeroed with sights set at 325 at 25m and then clicked back to 300 for duty. An M4 with buis is zeroed at the 300 mark at 25 meters for the air force and army(as faras I know) zeros at the line for the matech buis.

Re: 5.56x45 Trajectory Question
At 33 yards the trajectory is the same as it is at 300 yards. I know that doesnt answer your question exactly, but should point you in the right direction. In the Marine Corps we zero our rifles at 33 yards using scaled down 300 yard targets. Balastically at 33 yards the bullet is still rising in its arc and is at the same height as it is at 300 yards. Hope this helps.

Repeat zero for M193 is:
25 yard zero @ 374
50 yard zero @ 210
Here are a few drop charts. I have some better ones but they are in a power point and won't transfer with out some reconfiguring.
Edit to add- the spacing won't work so the charts may be difficult to read.
