I've used A 2230, 2460 and LT-32 and am about to use some 2200. I've also used IMR 3031 and 4198 and recently bought a couple of pounds of Shooter's World Tactical Rifle to try out. I haven't run the A 2200 or SW powders yet but the others performed well for me with 55 and 62 grain bullets. It's about time to load up a couple of batches of 223, since I burnt up around 300 rounds or so today at the range.
