Re: 223 load suggestions???
Always include the pill weight as some powders are "recommended" for heavier pills than other.
RL-15 progressively is +/- .3 grain in my Dillon .(usually on the + side)
Ramshot TAC +/- .2 Recommended for 60 +
BLC-2 +/- .2 Lighter pills
Win 748 is a Ball meters sweet also
Varget, the favorite, does not meter as well as any of these.
Be advised that temperature sensitivity may be an issue for you, based on your location. 3K rounds may take you though a change of season. Not me, it's cold down here when the temp is below 50.
