NEI double cavity .41 Colt mold, 205 grains.
Cast with wheel weights the bands' diameters measured:
Front .409" diameter
Rear .386" diameter
The dark color is release agent sprayed on before I received the mold. Haven't bothered to clean it off. These pictures are from laying the mold on my scanner at home. The distortion in the photo of the cavities (at the bullet base) is only photographic distortion (flare).
