If you're concerned about residue, you may want to try Win. 231, which I've heard, is a very clean burning powder, or the Vitavuori powders. These are noted for their clean-burning characteristics, altho a bit pricey. The VV powders listed for the 9mm Luger cartridge are N105, N310, N320, N330, N340, N350, & N3N37. I use N350 for my Colt Combat Eilte in .45acp, of course. Accurate & clean-burning, jd45.
