Interesting note after receiving a PM I had assumed that the Hornady manual was using a 24 inch barrel. The Nosler, Sierra and Hodgdon data DOES use a 24 inch barrel. THe Hornady manual states an Alexander Arms 18 inch barrel was used, with 30 grains of CFE 223 giving between 2400-2450 fps, if you add 4 inches of barrel and velocity it comes REALLY close. In my mind I am going with CFE 223 as I have gotten a handload at 31 grains of CFE 223 behind a 123 Gr ELD-M that is just under 1.5 inches which matches the factory load pretty closely through my barrel.
