You can use any data published by any of the other sources that have Unique data with 124 to 125 gr jacketed bullet. The link below is for Alliants data using 124gr JHP Gold Dots wich can be used for the FMJ. Reduce 10% for star load.

What about the OAL? The GDHP is shorter than the FMJ-RN. How do I adjust for the difference.
