Forgot to mention, Ramshot Magnum has given me the best velocity, accuracy, and consistency. The last 5 I ran over the Chrono back in Aug showed an extreme spread of 27 and SD of 8. The stuff meters like a dream through a Culver style measure as well. Should easily be able to get +/- .2gn with just about any dropper and consistent technique, my Harrell's is +/- .1 with Magnum.
