CJF,
The 366408 bullet is also too heavy (read long) for some(newer) 9.3x72Rs, so I also have one of my molds cut back to about 200 grains. My favorite bullet for the 9.3s is a really blunt nose 208gr from Hensley & Gibbs. It is their # 512c, but it is very hard to find on the used mold market. A 512a or 512b can be shortened similar to the 366408, if you can find one. The bullets from my mold drop out at .368" which allows sizing to use in different diameter barrels. HalfaDouble is also correct about Accurate Molds being really nice, although I have never tried the 37-196B.
