Tried several searches didn't find anything.
Had a friend help me the other day. Put up a piece of white paper at 100 yds with a line  for the 100 yd zero. Used a level and slid it down and marked the hold over points starting with the 300 and further.  
The following is what I came up with.
300- 3.125" for 9.375" drop @300 yds. Most loads are 12-13" low at 300 yds
400- 6.5" for 26" drop @ 400 yds
500- 9.625" for 49.375" drop @ 500 yds
600- 15" for 90" drop @ 600 yds
700- 20.75" for 145.25" drop @ 700 yds
800- 28.875" for 232" drop @ 800 yds
I want to build a load that will come close to matching up with the holdover lines. Any help ideas would be greatly appreciated. E-mailed Trijicon but haven't recieved a reply yet.

Forgot to factor in one important thing. Height of sight above bore.
Looks like a 60 grain Ballistic Tip @2925 fps comes pretty close given my shooting conditions, elevation, temp., etc..
