The nice thing about reloading the .308 and .223 is they both like some of the same propellants.What's worked for me in both are in this order:h-4895 ,imr4895 ,varget,748 ,and blc2.I would suggest everyone that loads rifle cartridges have one or more brands of 4895.I try 4895 in every load that has a listing for them.It's not always the best choice but it usually gives a useable load and often gives a great load.
