Need help with trajectory information

Can anyone help me with the trajectory for a .223.
Here are the variables: 1. ammo is Ultramax 55 gr Nosler Ballistic Tip; 2. per Ultramax, the ballistics for the round are 3000 ft/sec muzzle velocity and 1099 ft-lb muzzle energy ( I don't know what barrel length they use for these results ); 3. the rifle being used is an AR build with an 18 inch barrel length ; 4. the rifle has a flattop receiver and uses a Larue mount for the Leupold---this puts the center of the optic approximately 2.75 inches above the center of the bore.
The rifle has been zeroed for 100 yards. What I'm trying to find out is: 1. what does the bullet flight path look like per the variables listed...in other words, is the trajectory still rising at 100 yards ; 2. where would the POI be at 200,300,400 yards.
I apologize for the limited amount of information. I don't have a chronograph and I don't have access to a range beyond 100 yards at this time. I realize that any info will be approximate, but appreciate any info regardless.
If no one has the software or tables to calculate this information, can you direct me to a website or source to answer my questions.
Thanks in advance
Jack

I could run those numbers for you but I think that you'll have more fun using a program to help you solve the question for yourself. There are others available also but try this one first and see if you like it.
Let us know if you need more help.
Use this link for a good ballistics program that is free to download named Point Blank:
