I've found the Missouri Bullets coated and beveled Keiths shoot well as 44 specials in my two Vaqueros (one magnum, one special) and in my GP100 44 special. These days I shoot 7.5gr Skeeter loads, and 5.5gr reduced loads for plinking. Years ago, when I had two Redhawks, I loaded a lot of flat base Keiths (from a local caster who sold at an LGS), and they shot full power Keith loads well. Leading was very heavy. They may have been a little soft (claimed to be 18's), and I shied away from the flat base afterwards. I especially like Missouri's flat faced round nose for Cowboy rounds.
