I finaly started reloading 223 after getting all the componets together. I landed on 3031 as it was the first powder I found that I had data on. It has worked well, letting me hit my target and working fine in my rifle. The only problem I have had is getting it to meter. The last batch I did, I ended up weighing every throw, and was able to use about half of the throws. I can make this work, but I will not put the 223 on my progressive unlit I find something that will meter better. I had charges that were +- .6 grains, on a load that had a w.5 grain range min to max. I think i will start looking for a new powder now, as I have about a half pound left anyhow.
