I want to reload 5.56 for my AR. However; I haven’t found any recipes. I can find 223 with the 77gr SMKs I would like to use but no 5.56 info. Does everyone just load the 223 recipes and purchase 5.56?
I don't have any published data for Sierra bullets but the eight edition Hornady loading manual has 223 data and also a section on 223 "service rifle" data for 75 and 80 grain bullets. The seventh edition Nosler loading manual has 5.56 Nato data and lists loads for 77/80 grain bullets.
The Hornady Handbook of Cartridge Reloading 8th Edition has a section titled
223 Remington Service Rifle Data , it is geared strictly for AR-15 rifles .
The powders , primers and bullets in this section were all developed and tested in AR-15 service rifles ...might be something to check out .
