I just bought some reloading dies for 223 and I would like to reload some plinking rounds for my sons ar. I cant seem to find any good powder for the 223 rounds. All I have is titegroup, norma 204 , and norma 205. Would any of these be safe to load some 223 rounds with. I seen some data for titegroup but you only use 3.1 grains. I wonder if this will make the action work properly.
