I have dumped so many of the different powders suited for 223/5.56 that it's funny. The 223 I'm guessing will perform for plinking with anything that will burn. Buit like was said you find one that will make accurate plinking round then that is also a hunting round. I load so many powders cause had abundance of powders that would only go towards the AR and not work so well in bolt guns. I load plinking loads that don't push case capacity.
