melchar: I have an extra single-cavity #429251 (blocks only) the standard 255-gr. .44 Russian plain-base round-nose. (The #429384 250-grainer for the .44 Special is similar and interchangeable.) Mine is an older. Ideal-marked (1950's or so) set without vent grooves, slightly used but in good shape. It was sent me by mistake for the #429215 I had ordered from another collector for $45 + 3.00 shipping. You can have it for that amount. If interested, send me a PM with your s-mail address; you can pay me after you have checked it out. floodgate
