Greetings, I just got started casting and would like suggestions on what constitutes an acceptable variation in boolit weight. I have been casting some boolits for a .416 Ruger. Most come out within a .5 grain range. Mold is a brass NOE .418 350 gr RNFP. Boolits are dropping out at 345.5 +/- .5 grain with a few outliers that go straight back into the pot. What factors can contribute to more consistent boolit weights? Thanks,
