The older powders are good and I run alot of 3031, 4064 and 4895 in my small capacity cases but they are a pain to run through a measure so I pretty much use them for some of my low volume rounds like 5.6x50R, 25-204, 250 Sav. I don't shoot my 223 very often it is kind of a loaner or backup rig, it does dote on 3031 and 50gr NBT's though. For rounds I shoot alot of H-380, H-335, Benchmark and 748 see alot of uses because the run through the measure so nice.
