I understand the differences between 223 and 556 but my problem is Hornady reloading manual only goes to 60ngr bullets in their 223 loads and any bigger loads are service rifle or AR designated. I have a custom barrel for a Desrt Tech Conversion designed around shooting 75/77 gr bullets. Do I just use the bigger loads in 556 but being careful to work up? Do I still load my bullets to or just off lands since my magazine is big enough just like I do for other bolt action caliber guns?
Lastly, does it make any difference whether I use 223 or 556 brass so long as they are same brand and used in any load workup?
Thanks for any input. As soon as I think I understand it....I have to start all over.../
