Hi Everyone. I am new to casting for centerfire rifles. I am looking for help determining load data for the .223 Remington using 70 gr bullets. I have the NEI 72gr GC-DD mold and the NOE 65gr FN-GC mold. The rifle is a Savage model 12 with a 1:9 twist. I haven't found any listings anywhere that indicate what powders or charges to use. I plan on using powder coating and either straight linotype or a slightly diluted version. Feel free to correct any of the above details. Any help would be much appreciated.
