Just a heads up. To run charges larger than 5 grains, it would be best to use the LARGE bar supplied with the machine. Mine had the small bar/spacer installed from the factory. It worked okay up to about 5.6g, but anything above that it got inconsistent charges. After installing the large bar, charges were + or- .1g when not right on the money. So the already out there info about using the large bars in the 550's and 650's also holds for the SDB's......Buck
