Thanks for the replies. I've used W231, Unique, Titegroup and am currently using Bullseye which I find to be a pretty dirty powder. I was looking for a clean burning powder that also has some room for loading heavier bullets. I know a lot of people swear by W231 and Titegroup, but neither powder can reach military ball velocities with a 230gr FMJ. I see, on the Alliant website, that they claim Unique is now "cleaner burning". Might have to try some, again.
